@ -39,6 +39,9 @@ To check group membership before authenticating:
* define( 'LDAPAUTH_GROUP_ATTR', 'memberof' ); // (optional) LDAP groups attr
* define( 'LDAPAUTH_GROUP_REQ', 'the-group;another-admin-group'); // (only if LDAPAUTH_GROUP_REQ set) Group/s user must be in. Allows multiple, semicolon delimited
To define the scope of group req search:
* define( 'LDAPAUTH_GROUP_SCOP', 'sub' ); // if not defined the default is 'sub', and will check for the user in all the subtree. The other option is 'base', that will search only members of the exactly req
To define the type of user cache used:
* define( 'LDAPAUTH_USERCACHE_TYPE', 0); // (optional) Defaults to 1, which caches users in the options table. 0 turns off cacheing. Other values are currently undefined, but may be one day
