Let me understand, because it's still really bad explained: do you need to give sudo access to a group of users? Or do you need to simply give rwx permission to a certain group?

I Apologies....Right one is "do you need to give sudo access to a group of users".


Thank You

If you try "man sudo" (under "FILES") it tells you which file under "/etc/" contains the configuration for "sudo" -- it sounds like you haven't tried that yet (but maybe you did, you really need to elaborate more on your questions and what you have tried so far!)

Within the "sudo" configuration file, there are lots of commented examples -- you can easily alias a list of commands and grant permissions for those to individual users or groups.

BUT - if I understand your wish, it is to:
   - Grant to user "ABCD" (on multiple servers) the ability to:
     - "su" to accounts with names starting with "CDE" or ending with "XYZ".

It appears you can configure "sudo" to run "su" with your desired arguments, but there doesn't seem to be any pattern-matching capability, so you would need to configure it to handle each target user name.

If there are more than a few, or if it changes often  you could easily create a small program (should take about 20-30 lines of C) to:
  1- confirm the UID or GID of the user (optional if run via "sudo"),
  2- confirm that the requested username matches the desired criteria,
  3- exec "su" with the desired parameters.

You can either create this program as SETUID root or allow it with "sudo"  The former is easier, but requires you be careful in step #1.  But "sudo" could do this for you and provide you with some record-keeping about when the program was used.

It would be possible, but is probably a security hole, to create this program as a shell script -- can anyone enlighten us/me if "sudo" grants on shell scripts are considered safe or bad?

=====

An entirely different solution would be to install public keys in target users' ~/.ssh directory and allow access via "ssh".  Might be harder to setup/configure but I can't tell from your description.
