Seafile after upgrade to 12.0.7 Old libraries are not Found

With old ldap connection login_attr was email
If my email is arahman@email.com it shows me arahman as owner
But after upgrade to New version it shows me givenName from LDAP
But new account created old account with old libraries are missing!

Please let me know the configuration that I missed

How big of an upgrade did you do? Was it like 12.0.6 to 12.0.7, or like 10.0.2 to 12.0.7? I suspect it was a big update, because back in the upgrade to version 11 there were some changes to the way LDAP was connected to seafile accounts. The details are here: Upgrade notes for 11.0.x - Seafile Admin Manual

I have updated from 11 to 120.0.7

Also Library transfer from one user to another user seems like not working ! In my case i have checked this with my Admin user.
