Security exception on host string. USER ACCESS DENIED.

Cause
When trying to create a user with Adminsuite by placing the home directory on a
system remote from the NIS+ server, the user gets this error message:
Security exception on host hostname. USER ACCESS DENIED.
The user identity (555)username was received, but that user
is not authorized to execute the requested functionality
on this system. Is this user a member of an appropriate
security group on this system ?
(Function: class directory method create_dir)
The user can use rsh(1) to access the remote machine and create a home directory
on the system.
Action
The user was not in the system administration group NIS+ tables.
# niscat group.org_dir | grep sysadmin
sysadmin::14:
Add the user name to the system administration group.
