No SysLog on Windows

* Better plugin build for darwin

* add link to documentation, only discovered it while perusing issues list (#276)

* Plugin: Unix PAM Authentication (https://github.com/glauth/glauth/pull/263) (#277)

* Plugin: Unix PAM Authentication (#263)

* Add plugin using pam authentication

Adds an additional plugin which us authenticating against
the PAM unix backend and exposing users and groups local
to the machine glauth is running on.

This can be used to expose local users for authentication
in other services which support ldap only.

* plugins: pam: Rewrite Bind() to use ldapopshelper

Modernizes the implementation of Bind() to make use of the helper
functions provided by LDAPOpsHelper.

In order to support custom authentication the existing config.User
has received an additional PassAppCustom property which allows to
specify a custom authentication callback for a user.

In case of the PAM backend this will be used to authenticate against
the local PAM database.

* plugins: pam: Rewrite Search() to use ldapopshelper

Modernizes the implementation of Search() to make use of the helper
functions provided by LDAPOpsHelper.

* plugins: pam: Capability through group membership

Adds a configuration option which decides if a user gets the search
capability or not based on the group memberships of a user.

* plugins: pam: Apply formatting

Runs gofmt and go get on all changes done earlier

* plugins: pam: Address feedback from CodeClimate

- reduce code similarity
- document new exports
- address casing of variables and functions
- reduce complexity of FindPosixGroups()
- reduce complexity of FindPosixAccounts()
- fix else branch in ldapopshelper

 Use it to centralize account management across your Linux servers, your OSX machines, and your support applications (Jenkins, Apache/Nginx, Graylog2, and many more!).
 
-### Contributing
-- Please base all Pull Requests on [dev](https://github.com/glauth/glauth/tree/dev), not master.
-- Format your code autonmatically using `gofmt -d ./` before committing
+<hr>
+
+### Documentation
+
+<h4 align="center">:point_right: The latest version of GLauth's documentation is available at https://glauth.github.io/ :point_left:</h4>
+
+<hr>
 
 ### Quickstart
-This quickstart is a great way to try out GLAuth in a non-production environment.  *Be warned that you should take the extra steps to setup SSL (TLS) for production use!*
 
-1. Download a precompiled binary from the [releases](https://github.com/glauth/glauth/releases) page.
-2. Download the [example config file](https://github.com/glauth/glauth/blob/master/sample-simple.cfg).
-3. Start the GLAuth server, referencing the path to the desired config file with `-c`.
-   - `./glauth64 -c sample-simple.cfg`
-4. Test with traditional LDAP tools
-   - For example: `ldapsearch -LLL -H ldap://localhost:3893 -D cn=serviceuser,ou=svcaccts,dc=glauth,dc=com -w mysecret -x -bdc=glauth,dc=com cn=hackers`
-
-### Make Commands
-
-Note - makefile uses git data to inject build-time variables. For best results, run in the context of the git repo.
-
-*make all* - run build binaries for platforms
-
-*make fast* - run build for only linux 64 bit
-
-*make run* - wrapper for the 'go run' command, setting up the needed tooling
-
-*make plugins* - build additional (SQL) plugin backends
-
-*make test* - run the integration test on linux64 binary
+Get started in three short [steps](https://glauth.github.io/docs/quickstart.html)
 
 ### Usage:
 ```
@@ -97,214 +78,20 @@ Here's a sample config wth hardcoded users and groups:
   name = "superheros"
   gidnumber = 5501
 ```
-To create the password SHA hash, use this command: `echo -n "mysecret" | openssl dgst -sha256`
 
-Instead of a local configuration file, GLAuth can fetch its configuration from S3.  This is an easy way to ensure redundant GLAuth servers are always in-sync.
-```unix
-glauth -c s3://bucketname/glauth.cfg
-```
-In order to use S3, you must set your AWS credentials.  Either:
-
-1. set the -K and -S command-line flags  **OR**
-2. set the AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environment variables.
-
-More configuration options are documented here: https://github.com/glauth/glauth/blob/master/sample-simple.cfg
-
-### Chaining backends
-
-This can be used, for instance, to inject support for Two Factor Authentication for backends that do not support the feature natively:
-
-```
-[[backends]]
-  datastore = "ldap"
-  servers = ["ldap:s//localhost:390"]
-
-[[backends]]
-  datastore = "config"

-### OpenSSH keys:
-GLAuth can store a user's SSH authorized keys.  Add one or more keys per user as shown above, then setup the goklp helper: https://github.com/appliedtrust/goklp
-
-### Strong Passwords
-If you are currently using sha256 passwords (`passsha256` or `passappsha256`) moving to strong, salted paswords is recommended. Simply switch to `passbcrypt` and/or `passappbcrypt` password types. Currently (2021) 2<sup>12</sup> is a reasonably good value, depending our your server's CPU.
-
-### Two Factor Authentication
-GLAuth can be configured to accept OTP tokens as appended to a users password. Support is added for both **TOTP tokens** (often known by it's most prominent implementation, "Google Authenticator") and **Yubikey OTP tokens**.
-
-When using 2FA, append the 2FA code to the end of the password when authenticating. For example, if your password is "monkey" and your otp is "123456", enter "monkey123456" as your password.
-
-#### TOTP Configuration
-To enable TOTP authentication on a user, you can use a tool [like this](https://freeotp.github.io/qrcode.html) to generate a QR code (pick 'Timeout' and optionally let it generate a random secret for you), which can be scanned and used with the [Google Authenticator](https://play.google.com/store/apps/details?id=com.google.android.apps.authenticator2&hl=en) app. To enable TOTP authentication, configure the `otpsecret` for the user with the TOTP secret.
-
-#### App Passwords
-Additionally, you can specify an array of password hashes using the `passappsha256` for app passwords. These are not OTP validated, and are hashed in the same way as a password. This allows you to generate a long random string to be used in software which requires the ability to authenticate.
-
-However, app passwords can be used without OTP as well.
-
-#### Yubikey Configuration
-For Yubikey OTP token authentication, first [configure your Yubikey](https://www.yubico.com/products/services-software/personalization-tools/yubikey-otp/). After this, make sure to [request a `Client ID` and `Secret key` pair](https://upgrade.yubico.com/getapikey/).
-
-Now configure the `yubikeyclientid` and `yubikeysecret` fields in the general section in the configuration file.
-
-To enable Yubikey OTP authentication for a user, you must specify their Yubikey ID on the users `yubikey` field. The Yubikey ID is the first 12 characters of the Yubikey OTP, as explained in the below chart.
-
-![Yubikey OTP](https://developers.yubico.com/OTP/otp_details.png)
-
-When a user has been configured with either one of the OTP options, the OTP authentication is required for the user. If both are configured, either one will work.
+More configuration options are documented [here](https://glauth.github.io/docs/file.html) and in this [sample file](https://github.com/glauth/glauth/blob/master/v2/sample-simple.cfg)
 
 ### Backends:
-For advanced users, GLAuth supports pluggable backends.  Currently, it can use a local file, S3 or an existing LDAP infrastructure.  In the future, we hope to have backends that support Mongo, SQL, and other datastores.

+For advanced users, GLAuth supports pluggable backends.  Currently, it can use a local file, S3 or an existing LDAP infrastructure.  Through the use of optional plugins, you can connect SQL databases, PAM, and other datastores.

 ```toml
 [backend]
   datastore = "ldap"
   servers = [ "ldaps://server1:636", "ldaps://server2:636" ]
 ```
 
-### Production:
-Any of the architectures above will work for production.  Just remember:
-
- * Always use legit SSL certs for production!
-
-# Other Architectures
-A small note about other architectures: while I expect the code is, for the most part, system-independent, there is not a good (and free) CI system which can be easily used to continuously test releases on ARM, BSD, Linux-32bit, and Windows. As such, all of the non-linux-64bit packages are provided as is. The extent of testing on these packages consists solely of cross-compiling for these architectures from a linux 64 bit system.
-
-We will accept PRs which fix bugs on these platforms, but be aware these binaries will not be tested regularly, and instead are provided for the convenience of those who feel comfortable with this.
-
-### Building:
-You'll need go-bindata to build GLAuth. Then use the Makefile.
-```unix
-go get github.com/jteeuwen/go-bindata/...
-make all
-```
-
-# Logging
-- using logr with increasing verbosity
-  - 0 you always want to see this
-  - 1 common logging that you might *possibly* want to turn off (error)
-  - 2 warn
-  - 3 notice
-  - 4 info
-  - 6 debug
-  - 8 trace
-  - 10 I would like to performance test your log collection stack
-- errors really are errors that cannot be handled or returned
-  - returning a proper LDAP error code is handling an error
-
-# Testing
-
-Of course, a core set of tests is being run by Travis CI. However, when developing new features/refactoring, a more comprehensive regression testing suite is needed.
-
-You can run `go test` to execute the tests found in `glauth_test.go` -- better, if it is installed, you can run [goconvey](https://github.com/smartystreets/goconvey)
-
-Since some tests cover TOTP, you will first need to install `oathtool` in your environment.
-
-In order to test GLAuth against an LDAP backend, you will need docker. Run this command:
-```
-docker run \
-    --rm \
-    -d \
-    -p 389:389 \
-    --name openldap-service \
-    --hostname ldap-service \
-    --env LDAP_ORGANISATION="GLauth" \
-    --env LDAP_DOMAIN="glauth.com" \
-    --env LDAP_ADMIN_PASSWORD="password" \
-    --env LDAP_CONFIG_PASSWORD="password" \
-    --env LDAP_BASE_DN="dc=glauth,dc=com" \
-    -v $PWD/misc/openldap/config:/etc/ldap/slapd.d \
-    -v $PWD/misc/openldap/db:/var/lib/ldap \
-    osixia/openldap:latest
-```
-
-Refer to [this page](https://github.com/glauth/glauth/wiki/Quick-openldap-setup-to-test-LDAP-backend) for a somewhat more in-depth overview of testing with OpenLDAP.
-
-# Compatibility
-
-While our stated goal for GLAuth is to provide the simplest possible authentication server, we keep finding an increasing number of client appliances that are asking fairly "existential" questions of the server. We have been working on providing answers these clients will find satisfactory.
-
-### Root DSE
-
-RFC 4512: "An LDAP server SHALL provide information about itself and other information that is specific to each server.  This is represented as a group of attributes located in the root DSE"
-
-Test: `ldapsearch -LLL -H ldap://localhost:3893 -D cn=serviceuser,ou=svcaccts,dc=glauth,dc=com -w mysecret -x -s base "(objectclass=*)"`
-
-### Subschema Discovery
-
-RFC 4512: "To read schema attributes from the subschema (sub)entry, clients MUST issue a Search operation [RFC4511] where baseObject is the DN of the subschema (sub)entry..."
-
-Test: `ldapsearch -LLL -o ldif-wrap=no -H ldap://localhost:3893 -D cn=serviceuser,ou=svcaccts,dc=glauth,dc=com -w mysecret -x -bcn=schema -s base`
-
-By default, this query will return a very minimal schema (~5 objects) -- you can ask GLAuth to return more comprehensive schemas by unpacking, in the `schema/` directory, the OpenLDAP or FreeIPA schema archives found in the `assets/` directory.
-
-### LDAP Backend: "1.1" attribute
-
-RFC 4511: "A list containing only the OID "1.1" indicates that no attributes are to be returned."

-# GLAuth Plugins
-
-This folder contains plugins; that is, backends that are not compiled in GLAuth by default.
-
-To quote 'Butonic' (Jörn Friedrich Dreyer):
-
-> Just keep the 'lightweight' in mind.
-
-To build either back-end, type
-```
-make plugin_name
-```
-where 'name' is the plugin's name; so, for instance: `make plugin_sqlite`
-
-To build back-ends for specific architectures, specify `PLUGIN_OS` and `PLUGIN_ARCH` --
- For instance, to build the sqlite plugin for the new Mac M1s:
- ```
-make plugin_sqlite PLUGIN_OS=darwin PLUGIN_ARCH=arm64
- ```
-
-## Database Plugins
-
-To use a database plugin, edit the configuration file (see pkg/plugins/sample-database.cfg) so that:
-
-```
-...
-[backend]
-  datastore = "plugin"
-  plugin = "dynamic library you created using the previous 'make' command"
-  database = "database connection string"
-...
-```
-so, let's say you built the 'sqlite' plugin, you would now specify its library: `database = sqlite.so`
-
-### SQLite, MySQL, Postgres
-
-Tables:
-- users, groups are self-explanatory
-- includegroups store the 'includegroups' relationships
-- othergroups, on the other hand, are a comma-separated list found in the users table (performance)
-
-Here is how to insert example data using your database's REPL (more detailed information can be found in pkg/plugins/sample-database.cfg)
-
-```sql
-INSERT INTO groups(name, gidnumber) VALUES('superheros', 5501);
-INSERT INTO groups(name, gidnumber) VALUES('svcaccts', 5502);
-INSERT INTO groups(name, gidnumber) VALUES('civilians', 5503);
-INSERT INTO groups(name, gidnumber) VALUES('caped', 5504);
-INSERT INTO groups(name, gidnumber) VALUES('lovesailing', 5505);
-INSERT INTO groups(name, gidnumber) VALUES('smoker', 5506);
-INSERT INTO includegroups(parentgroupid, includegroupid) VALUES(5503, 5501);
-INSERT INTO includegroups(parentgroupid, includegroupid) VALUES(5504, 5502);
-INSERT INTO includegroups(parentgroupid, includegroupid) VALUES(5504, 5501);
-INSERT INTO users(name, uidnumber, primarygroup, passsha256) VALUES('hackers', 5001, 5501, '6478579e37aff45f013e14eeb30b3cc56c72ccdc310123bcdf53e0333e3f416a');
-INSERT INTO users(name, uidnumber, primarygroup, passsha256) VALUES('johndoe', 5002, 5502, '6478579e37aff45f013e14eeb30b3cc56c72ccdc310123bcdf53e0333e3f416a');
-INSERT INTO users(name, mail, uidnumber, primarygroup, passsha256) VALUES('serviceuser', "serviceuser@example.com", 5003, 5502, '652c7dc687d98c9889304ed2e408c74b611e86a40caa51c4b43f1dd5913c5cd0');
-INSERT INTO users(name, uidnumber, primarygroup, passsha256, othergroups) VALUES('user4', 5004, 5504, '652c7dc687d98c9889304ed2e408c74b611e86a40caa51c4b43f1dd5913c5cd0', '5505,5506');
-```
-This should be equivalent to this configuration:
-```text
-[[users]]
-  name = "hackers"
-  uidnumber = 5001
-  primarygroup = 5501
-  passsha256 = "6478579e37aff45f013e14eeb30b3cc56c72ccdc310123bcdf53e0333e3f416a" # dogood

-
-[[groups]]
-  name = "caped"
-  gidnumber = 5504
-  includegroups = [ 5502, 5501 ]
-```
-and LDAP should return these `memberOf` values:
-```text
-uid: hackers
-ou: superheros
-memberOf: cn=caped,ou=groups,dc=militate,dc=com
-memberOf: cn=civilians,ou=groups,dc=militate,dc=com

-memberOf: cn=caped,ou=groups,dc=militate,dc=com
-memberOf: cn=lovesailing,ou=groups,dc=militate,dc=com
-memberOf: cn=smoker,ou=groups,dc=militate,dc=com
-```
-If you have the ldap client package installed, this can be easily confirmed by running
-```
-ldapsearch  -H ldap://localhost:3893 -D cn=hackers,ou=superheros,dc=glauth,dc=com -w dogood -x -bdc=glauth,dc=com cn=hackers
-```
-and so on.
