Account lockout support in Solaris 10 when authenticating against Kerberos

[Yu, Ming]

Hi! Doug,
 
  So your point is that the account lockout feature is really not part of Kerberos, but part of Solaris?
 
  Because /etc/password is really the file where Solaris user accounts' passwords are stored.
 
  Please clarify.
 
  Thanks,
 
  Ming

See "man shadow".  /etc/passwd, NIS or LDAP can have *LK* to indicate
it is locked. I think it is the pam_unix_account that checks for this.
For a Kerberos account without a local password use something like NP
for the password.
