Description

The support for Yellowpages should not be installed unless it is required.

Rationale

NIS is the historical SUN service for central account management, more and more replaced by LDAP. NIS does not support efficiently security constraints, ACL, etc. and should not be used.

# CAUTION: This remediation script will remove nis
#	   from the system, and may remove any packages

#	   remediation AFTER testing on a non-production
#	   system!
