(LDAP AUTHENTICATION) TWO USERNAME FORMATS

[robertoroberto]

I want to have two user types (with different userName format) on the same LDAP server.
for example
uid=%s,o=xxxx
and
uid%s,ou=xxxx,o=xxxx

How can I do it?
How can I configure ldap and chaining configuration files?

[robertoroberto]

Is  anybody there?
There is a way to authenticate two users type on the same server?
for example
someone with usernameformat:uid=%s,o=xxxx
and others with username: uid%s,ou=xxxx,o=xxxx
?
Help me!!
(sorry for my english)
