Examples can be found on GitHub [1]. The exact column values for the
'ldapserver' table depend on what type of LDAP server and schema you
chose for your users. The file sqlite-sample.sql shows an example entry
for OpenLDAP with the 'posixAccount' object class (the latter uses
attributes 'mail' and 'uid').

If an LDAP server is configured for a given domain name, the column
ldapserver.attr_uid specifies the LDAP attribute used to determine the
user name; i.e. the value read from LDAP overrides server.user_name .
As long as you specify a non-null value for user_name, it does not
really matter which value you choose.
