Educated guess here...

Look at /etc/pam.d/omauth. I can't say for sure, but guessing by the
name, I'd say that's "om" for Open Manage. On my system it seems to
just reference the /etc/pam.d/system-auth configuration, which on your
system probably has the added protection from cpanel that you

So, you need to rewrite /etc/pam.d/omauth to be standalone, not
referencing the default system-auth requirements. So why does
pam_hulk.so not break system-auth? Maybe your system only has a 64 bit
pam_hulk.so, so 32-bit OMSA can't use it.

Try this command:

file `locate pam_hulk.so`

It will probably tell you that only one pam_hulk.so file is on the
system and that it is 64 bit. Maybe you can find a 32 bit pam_hulk.so
and not have to change the omauth configuration.

Too bad we don't have 64-bit Open Manage. Is anybody running 32 bit
servers any more?
