[Serusers] FW: SER Authentication Prob

[Ashling O'Driscoll]

If it helps any bit: I got the following errors from
/var/log/messages:

mod_init(): Unable to bind database module
init_mod(): Error while initialising module auth_db

Does anyone know how the above can be solved?...Im not that familiar
with linux so if I have to modify something, please make the
instructions as basic as possible!

Always apprecitive of help,
Aisling.

Hi all,

Hope somebody can help-I really am stumped as to why this won't work
and would really appreciate if someone could shed some light on the
problem....

I currently have SER set up and clients are registering successfully.
However I want clients to authenticate before they can register.
Howevere when I uncomment the relevant lines in the ser.cfg file, my
clients can't register. The only thing I can think of is that SER is
behind NAT and my clients may/may not be behind NAT....I have
included my ser.cfg file below...I have spent along time trying to
understand why this is happening so any help will be appreciated!

Thanks,
Aisling.
