Just a request for a quick clarification after reading through posts

We use autoadminlogon extensively on our machines and are implementing
Universal Password Policies in order to provide a way to logon to
Cisco wireless.

We were told that we must have NMAS installed on our machines in order
to set the Universal Password. So we've been going around updating all
our machines with Client 4.91sp4 and NMAS/NICI.

So far its been working fine but we are getting some odd problems with
some computers caused by address restrictions - 'unauthorized station'
errors - but only on certain computers.

Is it true that NMAS and autoadminlogon are incompatible and could be
causing this issue? If so, how do we implement Universal Password
which requires NMAS?
