I have a proposal. Let me know if this is a good idea to go about!

1. Generate seperate keytab file for each target.
2. Merge the keytabs into a common keytab file.
3. While configuring the target make sure they will use only the part
of the keytab ment for them.

This way the security is also not compromised.

Group,
Are there any other similar approaches?
