Description

When we do the below query the result takes long. Around 10-50 seconds.

Search base: ou=users,dc=xxx,dc=fi
Filter (&(cn=USERNAME)(objectClass=person))
Scope: Subtree

However the below query returns the result immediately
Search base: ou=users,dc=xxx,dc=fi
Filter (&(cn=USERNAME)(objectClass=*))
Scope: Subtree

Looking at the Partition settings it has Indexed attributes ObjectClass and cn.

First both queries took long. Then we added cn to the index and rebooted apacheDS and the second query got fast.

It seems like a bug that using ObjectClass in the query makes it slow all tough it is in the index.

It seems something similar was reported before DIRSERVER-2048, but it says it's fixed in M20 which we are using.
