Case sensntive usernames

I have an issue where some users accounts have been created with a capital letter in thier username in Active Directory LDAP. Because of this, OpenFire does not see the account as a valid user, it is looking for the member of a group that is ‘user.name’ but it is finding User.Name.

Is there a way to get around this or do I have to fix all the account names in LDAP?

Thanks

xmpp standards dont support case sensitive usernames.
