Comment # 4 on bug 1162421 from Juergen Mell

I installed the update once more yesterday and I think I have found the reason
why pam_winbind does not work anymore: it seems that ldconfig is not called
after the update for the samba-libs package is installed. I called ldconfig
manually today and restarted the sasl_authd service and everything is working
well now. Unfortunately this error does not occur immediately after the update,
as in my configuration the saslauthd process keeps running and using the old
version of pam_winbind until it is restarted later in the night. Then without
the new ldconfig data the new version of pam_winbind only finds the old version
of the library and fails. It might be a good idea to add the ldconfig command
to the RPM post-install script of samba-libs.
Thanks for your help!
