Last updated on DECEMBER 06, 2019

Applies to:

Oracle Unified Directory - Version 11.1.2.2.2 and later
Information in this document applies to any platform.

Symptoms

Searches that request the ismemberof attribute or reference it in the search filter are taking a long time to return results.  For example...

dn: uid=<UID.1>,cn=users,dc=<SUFFIX_DN>
isMemberof: <truncated>
isMemberof: <truncated>

real 0m28.577s
user 0m1.641s
sys 0m0.054s
