Error message for wrong or non specified user in /etc/crontab (RHBZ#1374264)

[hhorak]

This was initially reported as https://bugzilla.redhat.com/show_bug.cgi?id=1374264

Description of problem:

Error message "ERROR (getpwnam() failed)" when no user specified for jobs in /etc/crontab is not
so helpful at the first.
Maybe it will be more nice to have something like "no/wrong user-name specified for this job", or similar.

Steps to Reproduce:
Put some job in /etc/crontab without "user-name"

*/1 * * * * echo "bla" > /tmp/bla

Actual results:

Error message : Error message "ERROR (getpwnam() failed)

Expected results:

Error message : no/wrong user-name specified for this job

You've actually specified an user - user 'echo'.

And the user name is part of the message - see the 'echo' here:
Sep 8 14:53:01 vespa crond[1023]: (echo) ERROR (getpwnam() failed)

The reason why the getpwnam() failed can be various, it can be also that remote user identity server does not answer to queries.

So the message could be:
getpwnam() failed - user unknown or user identity resolution failure

Yes, exactly.

The reason why the getpwnam() failed can be various, it can be also that
remote user identity server does not answer to queries.

So the message could be:
getpwnam() failed - user unknown or user identity resolution failure

It makes sense to me.

This is already fixed. The current message is getpwnam() failed - user unknown. See b836b57
