You need to check the user's entry in the /etc/shadow file :
Where the "*" is should be a random string of text, the user's encrypted password.
Also check their entry in the /etc/passwd file and ensure they have a usable shell, that is the last field should be something like /bin/bash not /bin/false or /sbin/nologin.

We run Solaris 11. We have a root login constraint that we can login to the root only after doing a su from a generic account called "cloneroot". We somehow misplaced the password for the cloneroot account recently. So, we can't login to root. We have other accounts (eg. oracle) where we can login... (1 Reply)

ypchsh
yppasswd(1) General Commands Manual yppasswd(1)NAME
yppasswd, ypchfn, ypchsh - change your password in the NIS database
SYNOPSIS
yppasswd [-f] [-l] [-p] [user]
ypchfn [user]
ypchsh [user]
DESCRIPTION
In the old days, the standard passwd(1), chfn(1) and chsh(1) tools could not be used under Linux to change the users NIS password, shell
and GECOS information. For changing the NIS information, they were replaced by their NIS counterparts, yppasswd, ypchfn and ypchsh.
Today, this versions are deprecated and should not be used any longer.
Using the command line switches, you can choose whether to update your password -p, your login shell -l, or your GECOS field -f, or a com-
bination of them. yppasswd implies the -p option, if no other option is given. If you use the -f or -l option, you also need to add the -p
flag. ypchfn implies the -f option, and ypchsh -l.
When invoked without the user argument, the account information for the invoking user will be updated, otherwise that of user will be
updated. This option is only available to the super-user. If the yppasswdd daemon on the server supports it, you can give the root password
of the server instead of the users [old] password.
All tools will first prompt the user for the current NIS password needed for authentication with the yppasswdd(8) daemon. Subsequently, the
program prompts for the updated information:
yppasswd or -p
Change the user's NIS password. The user is prompted for the new password. While typing the password, echoing is turned off, so
the password does not appear on the screen. An empty password is rejected, as are passwords shorter than six characters. The user
will then be requested to retype the password to make sure it wasn't misspelled the first time.
ypchsh or -l
Change the user's login shell. The user is prompted for a new shell, offering the old one as default:
Login shell [/bin/sh]: _
To accept the default, simply press return. To clear the shell field in your passwd(5) file entry (so that the system's default
shell is selected), enter the string none.
ypchfn or -f
Change the user's full name and related information. Traditionally, some applications expect the GECOS field (field 4) of the
passwd(5) file to contain the user's real name (as opposed to the login name) plus some additional information like the office phone
number. This information is displayed by finger(1) and probably some other tools, too.
When setting the full name, ypchfn displays the following prompts, with the defaults in brackets:
Name [Joe Doe]:
Location [2nd floor, bldg 34]:
Office Phone [12345]:
Home Phone []:
To accept a default, simply press return. To clear a field, enter the string none.
