There is an issue when you want to test LDAP auth with the Beta 2.

Open "system/Login/Ldap.php"

Got to the line 110 and replace this:

$bind = ldap_bind( $this->ldap, 'uid=diradmin,cn=users,dc=bec,dc=local', $this->settings['server_pass'] );

By this:

$bind = ldap_bind( $this->ldap, $this->settings['server_user'], $this->settings['server_pass'] );

 

Done.  In the future please report bugs to the bug tracker, however.

It was more tutorial oriented for people who wants to test it more than report a bug that i'm pretty sure you already knew it. Explains why I didn't reported it, but I will in the future if it can helps. 

Always helps ... If they spotted every bug there wouldnt be any
