Description Kaushik Banerjee 2013-01-23 10:29:44 UTC

Description of problem:
Group lookup hangs for a minute if member dn is incorrect.

Version-Release number of selected component (if applicable):
1.9.2-74

How reproducible:
Always

Steps to Reproduce:
1. Add a group as follows:
dn: cn=Group_02,ou=Groups,dc=example,dc=com
gidNumber: 10120
objectClass: top
objectClass: groupOfNames
objectClass: posixGroup
cn: Group_02
member: uid=kuser1    <== I removed ",dc=example,dc=com"

2. Try to lookup the group
# time getent group Group_02

real    0m58.008s    <== Takes almost a minute to return back to shell
user    0m0.000s
sys    0m0.001s

Actual results:
Group lookup fails and takes a minute to come back to shell.

Expected results:

This is actually a cause of performance regression we were seeing. Closing as duplicate.
