This is not indicative of a bug in OpenLDAP Software
(slapd(8) or ldap(3)). Whether or not this is a bug
in the client you are using is beyond the scope of
the OpenLDAP Issue Tracking System. I suggest you
take questions regarding the client, apparently
a PAM LDAP module, to the firstname.lastname@example.org list.
This issue will be closed.
