This commit actually covers a few items. In future commits, I will keep features distinct. This is only happening this time around due to how long it took to merge this branch. Covered: - Database plugins (at this time: SQLite, MySQL, Postgres) - Backends acting as middleware: added the [[Backends]] configuration directive while retaining backward compatibility with [Backend] - Schema introspection (root DSE query with base scope) - When proxying, insert queried attribute back in upstream response, if absent, so that the LDAP library does not filter out all entries - When chaining backends, any backend can be used to inject OTP value in password, before reaching a non-OTP-aware backend (currently guarded by a True statement in case we find an issue (I did thoroughly test but you never know)) - Handling of special "1.1" attributes filter meaning "I do not want attributes" (RFC 4511, 4.5.1.8) - Support for "want types only" queries, even when proxying

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
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)
INSERT INTO users(name, unixid, primarygroup, passsha256) VALUES('hackers', 5001, 5501, '6478579e37aff45f013e14eeb30b3cc56c72ccdc310123bcdf53e0333e3f416a');
INSERT INTO groups(name, unixid) VALUES('superheros', 5501);
INSERT INTO groups(name, unixid) VALUES('crusaders', 5502);
INSERT INTO groups(name, unixid) VALUES('civilians', 5503);
INSERT INTO groups(name, unixid) VALUES('caped', 5504);
INSERT INTO groups(name, unixid) VALUES('lovesailing', 5505);
INSERT INTO groups(name, unixid) 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, unixid, primarygroup, passsha256) VALUES('user1', 5001, 5501, '6478579e37aff45f013e14eeb30b3cc56c72ccdc310123bcdf53e0333e3f416a');
INSERT INTO users(name, unixid, primarygroup, passsha256) VALUES('user2', 5002, 5502, '6478579e37aff45f013e14eeb30b3cc56c72ccdc310123bcdf53e0333e3f416a');
INSERT INTO users(name, unixid, primarygroup, passsha256) VALUES('user3', 5003, 5504, '6478579e37aff45f013e14eeb30b3cc56c72ccdc310123bcdf53e0333e3f416a');
INSERT INTO users(name, unixid, primarygroup, passsha256, othergroups) VALUES('user4', 5004, 5504, '6478579e37aff45f013e14eeb30b3cc56c72ccdc310123bcdf53e0333e3f416a', '5505,5506');
This should be equivalent to this configuration:
[[users]]
name = "hackers"
unixid = 5001
primarygroup = 5501
passsha256 = "6478579e37aff45f013e14eeb30b3cc56c72ccdc310123bcdf53e0333e3f416a" # dogood
[[users]]
name = "user1"
unixid = 5001
primarygroup = 5501
passsha256 = "6478579e37aff45f013e14eeb30b3cc56c72ccdc310123bcdf53e0333e3f416a" # dogood
[[users]]
name = "user2"
unixid = 5002
primarygroup = 5502
passsha256 = "6478579e37aff45f013e14eeb30b3cc56c72ccdc310123bcdf53e0333e3f416a" # dogood
[[users]]
name = "user3"
unixid = 5003
primarygroup = 5504
passsha256 = "6478579e37aff45f013e14eeb30b3cc56c72ccdc310123bcdf53e0333e3f416a" # dogood
[[users]]
name = "user4"
unixid = 5003
primarygroup = 5504
othergroups = [5505, 5506]
passsha256 = "6478579e37aff45f013e14eeb30b3cc56c72ccdc310123bcdf53e0333e3f416a" # dogood
[[groups]]
name = "superheros"
unixid = 5501
[[groups]]
name = "crusaders"
unixid = 5502
[[groups]]
name = "civilians"
unixid = 5503
includegroups = [ 5501 ]
[[groups]]
name = "caped"
unixid = 5504
includegroups = [ 5502, 5501 ]
and LDAP should return these memberOf values:
uid: user1
ou: superheros
memberOf: cn=caped,ou=groups,dc=militate,dc=com
memberOf: cn=civilians,ou=groups,dc=militate,dc=com
memberOf: cn=superheros,ou=groups,dc=militate,dc=com
uid: user2
ou: crusaders
memberOf: cn=caped,ou=groups,dc=militate,dc=com
memberOf: cn=crusaders,ou=groups,dc=militate,dc=com
uid: user3
ou: caped
memberOf: cn=caped,ou=groups,dc=militate,dc=com
uid: user4
ou: caped
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=user1
and so on.
