To run a (only) command with root privileges you can run sudo at the prompt.

But am able to run the "crontab" command in some other machine as a normal user.

It's probably a permissions issue on crontab binary.

Generally, you'll have the following:

/var/spool/cron - ower root:root with permissions 0700 (drwx------).
/usr/sbin/crontab - ower root:root with permissions 4755 (-rwsr-xr-x).

The 'crontab' binary is set up as 'suid', so it should run as any user.

If at some point the crontab binary had it's permissions changed (use 'rpm -V vixie-cron' to confirm that), it will cause this issue.

If this is all it is, then 'chmod 4755 /usr/bin/crontab' will fix it.

If it's not that, then show us the output of the following two commands:

/bin/ls -ld /var/spool/cron /usr/bin/crontab
/bin/rpm -V vixie-cron

No, my point is not that crontab cannot be run by user with normal user privileges.

My intent was to imply that in case the (a) command isn't executing as expected, the command can be easily run with higher privileges just by preceding the command with sudo.

Check the permissio for the user in the cronjob, by default the user will be having read only permission.
Change the permission of user to execute in cronjob and try once again.
