Hi Arthur,

it would be nice if nslcd could be configured to not log any occurrences
of "request denied by validnames option" or similar less critical but
potentially noisy logging.

Reasoning: On systems with nslcd, any tool which looks up arbitrary
strings as user name or similar will cause one line per lookup in the
syslog and hence may fill up the disk. (Luckily most syslog servers
noticed such bursts.)

This may sound far fetched, but it isn't: ccze is a log colorizer which
by default tries to recognize usernames and similar in the parsed log
file. If that log file is the log file nslcd is logging to, this causes
some kind of a loop until the syslog server suppresses further looping
for a while:

While doing this in one shell:
# echo foo=bar | logger

... the following happens in another shell:
# tail -f /var/log/syslog | ccze -A

Oct 31 14:36:44 snidget rsyslogd-2177: imuxsock begins to drop messages from pid 19433 due to rate-limiting

I'm not the first one who reported that. It already has been reported
back in 2008 against ccze itself[1], but has been considered a feature,
not a bug in ccze. I've finally realised the causality chain after
finding and reading [2] of 2011.

[1] http://bugs.debian.org/505926
[2] http://debianforum.de/forum/viewtopic.php?f=37&t=136642#p884948

Once the issue has been identified, it can be solved by adding "-o
nolookups" to the ccze command:

# tail -f /var/log/syslog | ccze -A -o nolookups

But I still would be happy if there would be a way to suppress these
less critical messages completely. Maybe adding some log level setting
or similar.

Thanks for reporting this bug.

This is actually a bit funny ;)

Indeed, nslcd can log several warnings that will be annoying if they
happen too often. In #567099 the proposed solution is to implement rate
limiting of such errors (actually the bug is regarding log entries about
problematic data in LDAP but the principal is the same).

If anyone is prepared to write a patch for this, I'll ensure that it
gets integrated. There is already a cache-like structure in nslcd for
caching dn to uid lookups. Something similar could be made for looking
up certain warnings.

Thanks,
