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".

passwd
PASSWD(1) BSD General Commands Manual PASSWD(1)NAME
passwd -- modify a user's password
SYNOPSIS
passwd [-i infosystem] [-l location] [name]
DESCRIPTION
Passwd changes the user's password. First, the user is prompted for their current password. If the current password is correctly typed, a
new password is requested. The new password must be entered twice to avoid typing errors.
The new password should be at least six characters long and not purely alphabetic. Its total length should be less than _PASSWORD_LEN (cur-
rently 128 characters) although some infosystems allow longer passwords. Numbers, upper case letters and meta characters are encouraged.
Once the password has been verified, passwd communicates the new password information to the authenticating host.
-i infosystem
This option specifies where the password update should be applied. Under Mac OS X 10.3, supported infosystems are:
netinfo
(default) The netinfo database containing the user's password. If no -l option is specified, the local netinfo database is
assumed.
file The local flat-files (included for legacy configurations).
nis A remote NIS server containing the user's password.
opendirectory
A system conforming to opendirectory APIs and supporting updates (including LDAP, netinfo, etc).
-l location
This option causes the password to be updated in the given location of the choosen infosystem. When changing only the local password,
pwd_mkdb(8) is used to update the password databases.
for netinfo,
location may be a domain name or server/tag
for file,
location may be a file name (/etc/master.passwd is the default)
for nis,
location may be a NIS domainname
for opendirectory,
location may be a directory node name
The super-user privilages are not required change a user's current password if only the local password is modified.
FILES
/etc/master.passwd The user database
/etc/passwd A Version 7 format password file
/etc/passwd.XXXXXX Temporary copy of the password file
