Our Ldap Configuration for authentication and authorisation was working fine with 1.14 Ldap Plugin but with upgrade to 1.15 Ldap plugin it cannot find groups.

Test Ldap Configuration Results but able to authenticate correctly
No LDAP group membership reported.
If the user is a member of some LDAP groups then the group membership settings are probably configured incorrectly.

The Group search base is same , if i rollback the ldap plugin to 1.14 all configuration works fine
