after installing McAfee LinuxShield 1.5.1 on one machine of our OES2
cluster, everything seems to be fine, except for login to the software's
own webpage.

When I try to login using the user "nails", I only get the error message
"Error: bad credentials".

I have already modified /etc/pam.d/nails and added lines for PAM
authentication (as I read in an other thread in this forum):

auth sufficient pam_nam.so
account sufficient pam_nam.so
password required pam_nam.so

While it solved the problem on my test server, on our cluster system the
problem stays the same.

I also tried adding two other versions of additional lines to the pam
file, but also no success.

Anybody having a solution for this problem?

Thanks in advance,
