cron uid:gui for every username

Question

So in the nutshell :

There was user John with 502:502.

After i deleted John and recreated him, his UID:GID changed to 504:504.

Cronjobs are still running under the John's crontab, but when the cronjobs are happening they are writing some files into /home/John in the name of 502:502.

It is quite a mess, and I am not sure what would be the easier way to solve it, either change current John's uid and gid to 502:502 - which could cause more problems with files the user was working since. But I was thinking that going somewhere to cron config and changing John's uid:gid from 502:502 to 504:504 there, inside cron.

Looked all over the place, but can not find it. Any ideas ?

EDIT: I am on CentOS 6

Answer 1

Try looking in /var/spool/cron for the user crontabs.

Answer 2

You probably have a name service caching daemon running on your system, try to restart it. Typical names contain something like nscd.

You can also check /var/spool/cron/crontabs/John (or the equivalent file) and make sure that the file has the correct permissions. Otherwise it may help to restart cron.
