ldap-agent needs to find slapd.stats file dynamically
Last modified: 2015-12-07 12:04:38 EST
Our SNMP subagent (ldap-agent) currently requires a full path to a DS instance in it's config file. It is hardcoded to look in the log subdirectory for the slapd.stats file. It also uses expects a config subdirectory to find the dse.ldif. This will no longer work now that DS has been restructured to follow FHS standards. The proposed fix changes the ldap-agent config to simply expect the instance name (i.e - slapd-foo). The subagent will then use this instance name to load the dse.ldif from the proper location in $SYSCONFDIR/$PACKAGE_NAME. The subagent will look up the value of nsslapd-tmpdir to find out where the slapd.stats file is for that particular instance. I also improved the error checking around processing the ldap-agent config file.

That's not going to work if the value for nsslapd-tmpdir wraps to the next line, which probably won't happen in production systems, but might in weird install cases or QA.
Created attachment 160880 [details] Revised Diffs Rich brings up a good point about dealing with wrapped lines in the dse.ldif. This new set of diffs addresses this concern by using the ldif parsing functions from the libldif library that is part of the Mozilla LDAP C SDK. I also did some error checking cleanup, particularly ensuring that we close any files that we opened if we encounter an error condition while processing the config. I have also tested that these changes work when there is a wrapped line for one of the attributes that we read in dse.ldif.
Nice!
Checked into HEAD. Thanks for the review Rich!
