Make sure that the shell entry in the /etc/passwd file exists. Then check the .profile, .login, .bashrc and/or .cshrc files in the users home directory for something odd (like an exit statement). If that all checks out, vi the /etc/shadow file and remove the password encryption (the second field between :'s). Then try to login in with a blank password. What error do you get when you try to su to the user from root. As root, try these and let us know what the results/output is:

passwd
PASSWD(5) File Formats and Conversions PASSWD(5)NAME
passwd - the password file
DESCRIPTION
/etc/passwd contains one line for each user account, with seven fields delimited by colons (":"). These fields are:
o login name
o optional encrypted password
o numerical user ID
o numerical group ID
o user name or comment field
o user home directory
o optional user command interpreter
The encrypted password field may be blank, in which case no password is required to authenticate as the specified login name. However, some
applications which read the /etc/passwd file may decide not to permit any access at all if the password field is blank. If the password
field is a lower-case "x", then the encrypted password is actually stored in the shadow(5) file instead; there must be a corresponding line
in the /etc/shadow file, or else the user account is invalid. If the password field is any other string, then it will be treated as an
encrypted password, as specified by crypt(3).
The comment field is used by various system utilities, such as finger(1).
The home directory field provides the name of the initial working directory. The login program uses this information to set the value of
the $HOME environmental variable.
The command interpreter field provides the name of the user's command language interpreter, or the name of the initial program to execute.
The login program uses this information to set the value of the $SHELL environmental variable. If this field is empty, it defaults to the
value /bin/sh.
