This allows you to check if your LDAP schema is compatible with LAM and to find possible problems.
LAM provides an external script to manage home directories and quotas. You can test here if everything is setup correctly.
If you get an error like "no tty present and no askpass program specified" then the path to the lamdaemon.pl may be wrong. Please see the lamdaemon installation instructions for setup details.
This will test if your LDAP schema supports all object classes and attributes of the active LAM modules. If you get a message that something is missing please check that you installed all required schemas.
If you get error messages about object class violations then this test can tell you what is missing.
