Description Kaushik Banerjee 2012-11-16 10:40:33 UTC
Description of problem:
ldap_connection_expire_timeout doesn't expire ldap connections

Version-Release number of selected component (if applicable):
1.9.2-13

How reproducible:
Always

Steps to Reproduce:
1. domain section in sssd.conf

[domain/LDAP]
debug_level = 0xFFF0
id_provider = ldap
ldap_uri = ldap://cobra.lab.eng.pnq.redhat.com
ldap_search_base = dc=example,dc=com
ldap_connection_expire_timeout = 100

2. # getent passwd puser1;netstat -antp | grep 389;sleep 105;netstat -antp | grep 389
puser1:*:2001:2001:Posix User1:/home/puser1:
tcp        0      0 10.65.201.200:40926         10.65.206.93:389            ESTABLISHED 7163/sssd_be        
tcp        0      0 10.65.201.200:40926         10.65.206.93:389            ESTABLISHED 7163/sssd_be

Actual results:
Connection doesn't expire after "ldap_connection_expire_timeout" is over.

Expected results:
Connection should expire

Comment 4 Jakub Hrozek 2012-11-17 19:56:15 UTC
FWIW, this regressed only when using non-authenticated connection. Authenticated connections including GSSAPI still timed out fine.

It's still a regression, though. A patch is on the upstream list.
