Re: solaris 10 caching credentials? Inactivated users allowed in via ssh

Brian,
It sounds like you're using the pam_unix module for authentication on 
the Solaris 10 client instead of the pam_ldap module.  The bind as the 
proxy user is to retrieve the crypted password hash of the account, 
which is then compared with the password given at login.
If you want LDAP account deactivation to affect logins to Solaris 
clients, those clients must use pam_ldap to authenticate against the 
LDAP server, instead of pam_unix.
Note also that deactivating a LDAP account will not prevent 
password-less rsh login with that account.
