Lost Admin password

[John Johnson]

Does anybody know a way to recover from a lost admin password.  We have an
ADSM server running on AIX, but no one knows the passwords to the admin
ID's.  I have been able to login to the server, but only as an
Analyst/Operator.  There are three ID's with System authority, two of which
are locked out.

 Is there a way to unlock/reset these ID's when logged into the AIX system
with root authority?


Thanks.
