Description Elena Zannoni 2005-08-01 16:09:29 UTC

+++ This bug was initially created as a clone of Bug #150748 +++

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.2) Gecko/20040803

Description of problem:
After changing the password on our NIS-Server, the client does not use the new
password while nscd is active. With deactivated nscd the new passwords are
delivered. Restarting nscd gives again the old password. Timeouts in
/etc/nscd.conf are the default values (600 sec), but I get the old password even
after 3 days

Version-Release number of selected component (if applicable):
glibc-2.3.4-2.fc3  nscd-2.3.4-2.fc3

How reproducible:
Always

Steps to Reproduce:
1. Change password on NIS Server
2. wait 30 min
3. getent passwd user
4. getent passwd | grep user
  

Actual Results:  "getent passwd user" gives me the old password hash, while nscd
is active
"getent passwd|grep user" gives me the new hash, same for "ypcat passwd"

Expected Results:  After the 10 minutes timeout I expect to se the new hash values

Additional info:

No information about any problems in /var/log/messages

Output from nscd -d -d -d:

12368: Access Vector Cache (AVC) started
12368: handle_request: request received (Version = 2) from PID 12376
12368:  GETFDPW
12368: provide access to FD 5, for passwd
