Re: [HTCondor-users] startd doesn't start

[Alessandra Forti <Alessandra.Forti@xxxxxxx>]

Hi Greg,

thanks for your reply. We don't have LDAP/NIS the users are local to the grid cluster. Puppet creates a condor user as well. CONDOR_IDS is set to 0.0. in both the 8.4.11 and 8.6.1 installation. I did enable D_FULLDEBUG but I cannot find any information about whatever user is used other than

03/18/17 20:23:47 Running as root.  Enabling specialized core dump routines
03/18/17 20:23:47 Daemon Log is logging: D_FULLDEBUG D_ALWAYS D_ERROR D_COMMAND

and then eventually the error reported.

cheers

In the StartLog files I have this error

03/17/17 08:20:35 ERROR: Attempt to initialize user_priv with root privileges rejected

When started as root, the startd spends most of it's runtime as a non-root user, for security reasons.  In those places where it needs root, it will setuid back to root temporarily, but then switch back to a non-root uid.

This error says that the startd is trying to switch effective user id to some non-root user, but the numeric id (or gid) of that non-root user is zero, which is clearly an error, and rather than run with improperly elevated privileges, the startd aborts.

So, it would be useful to know which user it is trying to run as, which a bit more of the log above this, especially running the startd with D_FULLDEBUG will show.  Also, the values of the config setting CONDOR_IDS may be involved.  This error can be caused if you are getting your passwd file entries from NIS or LDAP, and somehow the startd didn't load that library or configuration.
