Hi Mrs,

I have a Tacacs server to centralize autentication in my routers, switchs, cmts ... And I think I will use this infraestructure to centralize my authentication on my Linux Servers.

I found on my seachs on google a PAM module to tacacs.

Anyone know about or use this module?

Thanks,

Dud.

Dud,

i suppose you're talking of the tacacs+ client package published by some Polish guy (don't remember the name
right now). The pam_tacacs module works quite fine. Soem quirks when using tacacs 'accounting' (not to be confused
with PAM accounting, which is the equivalent to tacacs 'authorize'). There is a drawback in that the module supports only
one tacacs server. The workaround i took, was to stack the module twice, each one with a different tacacs server.
Don't forget to switch on encryption. My configuration was:

    auth        sufficient   pam_tacplus.so encrypt secret=FarAway server=10.13.0.22
    auth        sufficient   pam_tacplus.so encrypt secret=FarAway server=10.14.1.69

BTW the above package includes 'tacc', a small  line-mode tacacs client. A fine tool when debugging the tacacs environment.

Andreas
