System Administration Guide: Naming and Directory Services (NIS+)

Password Privilege Expiration in NIS+

You can set a specific date on which a user's password privileges expires. When a user's password privilege expires, that user can no longer have a valid password at all. In effect, this locks the user out of the system after the given date because after that date the user can no longer log in.

For example, if you specify an expire date of December 31, 1997, for a user named pete, on January 1, 1998 he will not be able to log in under that user ID regardless of what password he uses. After each login attempt he will receive a Login incorrect message.

Password Aging and Password Expiration in NIS+

Expiration of a user's password privilege is not the same as password aging.

Setting a Password Expiration Date in NIS+

Password privilege expiration dates only take effect when the user logs in. If a user is already logged in, the expiration date has no effect until the user logs out or tries to use rlogin or telnet to connect to another machine at which time the user will not be able to log in again. Thus, if you are going to implement password privilege expiration dates, you should require your users to log out at the end of each day's work session.

Note –

If you have Solaris Management Console tools available, do not use nistbladm to set an expiration date. Use Solaris Management Console tools because they are easier to use and provide less chance for error.

To set an expiration date with the nistbladm command:

nistbladm -m `shadow=n:n:n:n:n:n6:n' [name=login],passwd.org_dir


For example, to specify an expiration date for the user pete of December 31, 1995 you would type:

station1% nistbladm -m `shadow=n:n:n:n:n:9493:n' [name=pete],passwd.org_dir

Caution – Caution –

All of the fields must be filled in with valid values.

Turning Off Password Privilege Expiration in NIS+

To turn off or deactivate password privilege expiration, you must use the nistbladm command to place a -1 in this field. For example, to turn off privilege expiration for the user huck, you would type:

station1% nistbladm -m `shadow=n:n:n:n:n:-1:n' [name=huck],passwd.org_dir

Or you can use the nistbladm command reset the expiration date to some day in the future by entering a new number of days in the n6 field.
