I found out that Mozilla, is not able to add anything to an LDAP server, even if sufficient rights are given. I searched Bugzilla and found no bug corresponding to this, so I open this one. To use Mozilla in a Groupware application environment it is vital that the individual users can add their new contacts to the global LDAP Server through Mozilla Addressbook, so that other people my have access to it. I really don't want to stick with Outlook just for that.
