    A wild guess....

    Im pushing the boat out a bit here, so dont flame me....

    Is the nis master a redhat system?

    Ive seen a problem where the nis master is Solaris and when the password is
    changed on the Redhat system (workstation) the password is screwed up. Maybe
    its got something to do with MD5 (on the redhat system) vs a passwd encrypted
    password on the Solaris system.

    A passwd password is 8 characters long and an MD5 password is longer.

    Change the password on the nis master or slave.
