To create or edit the cron file of any user from root user. You can use this following command:
# crontab -u <user> -e
If the user wants to create or edit his on cron file by himself (without root user involvement), it is still possible by using this following steps:
However, as mentioned on the previous post, it is depends on how the /etc/cron.allow and /etc/cron.deny files are configured on your machine.
That is way too complicated. Any user that is allowed to submit cron jobs can edit their own crontab file with just:
You don't need special privileges unless you are editing someone else's crontab file.
The crontab utility runs with setUID root privileges so it can create the directory to contain the crontab file, the crontab file, change its owner to the user's UID with group cron, and then reduces privileges to run an editor for the user to update their own crontab file.

bcron-update
bcron-update(8) System Manager's Manual bcron-update(8)NAME
bcron-update - Update system crontabs.
SYNOPSIS
bcron-update path [ path ... ]
DESCRIPTION
bcron-update polls the named files or directories periodically to see if there are any new, changed, or removed files. When it detects
changes, it mirrors those changes into the crontab spool directory. bcron-update runs as root in order to be able to read system files
that would potentially be unreadable otherwise.
On Debian, if path is a directory, bcron-update skips files in this directory with names that do not solely consist of lower- and uppercase
letters ('a'-'z', 'A'-'Z'), digits ('0'-'9'), underscores ('_'), and hyphens ('-').
EXAMPLES
To mirror modern vixie-cron's behavior, use:
bcron-update /etc/crontab /etc/cron.d
ENVIRONMENT
BCRON_SPOOL
The spool directory for bcron. Defaults to /var/spool/cron.
BCRON_USER
After writing files and before moving them into their final location, bcron-update changes the ownership of the file to this user so
that bcron-sched can read them.
SEE ALSO bcron-sched(8)DIAGNOSTICS
bcron-update outputs three different kinds of messages about actions it is taking.
Rescanning /etc/cron.d
The named directory has been modified, and will be scanned to determine what files have been added or deleted.
-/etc/cron.d/oldfile
The named file no longer exists and will be removed from the spool.
+/etc/cron.d/newfile
The named file was either created or modified since the last scan, and will be copied into the spool.
