Currently using tikiwki (PHP) with LDAP authentication, and began experimenting with xwiki (Java) also with LDAP authentication. Both against an Active Directory server. With both systems you cannot authenticate a password with either a comma or a period, so suspect it is the underlying OpenLDAP libraries. The test password had both a comma and period, and the account is locked right now so I can't easily test which one or both are required to activate the bug.
I did try looking for this bug suspecting that it would have been reported, and didn't find it. Hope this isn't a duplicate.
