Public bug reported:
I'm running 64-bit Ubuntu Desktop 12.04.1, with kernel version
3.2.0-32-generic.
I have configured PAM LDAP authentication for several clients and this
problem is reproducible on each client system.
If I'm not running the name service cache daemon (nscd), I'm getting the
following errors when I attempt to start either 'acroread' or
'thunderbird':
(acroread:11520): GLib-WARNING **: getpwuid_r(): failed due to unknown user id
(537)
(thunderbird:11298): GLib-WARNING **: getpwuid_r(): failed due to: Connection
refused.
The solution so far has been to always keep the nscd service running.
However, after a recent update, nscd is now crashing each time it is
started.
Here is the output when running "strace nscd -d -d -d":
