I have openLDAP server up and running and trying to integrate it with Confluence. My LDAP structure looks like

DN :: uid=123, ou=users, dc=example, dc=com
uid :: 123
mail :: bjason@example.com
cn :: barbara
sn :: jason
userPassword :: test (plain test for now)

I have another similar entry in another branch (su) for "confluence admin", I did LDAP configuration in confluence and tested the bind with confluence user. Now for every user authentication I am assuming LDAP should be able to bind on any attribute other than DN. however I can not do that. when I try to login from confluence using mail & password, this is what I see in my slapd.d logs :

I guess I should be able to do LDAP_BIND with any attribute and LDAP should be able to search user's DN based on the attribute and authenticate him as I have laready provided valid DN and password (for confluence user), am I right here? Please let me know if its doable (should be) and what am I missing here ? I tried searching for this but couldn't find it on the web. Thanks for the help and support.
