TACACS+ and /etc/shadow

Hi. I'm trying to get Cisco's free UNIX based TACACS+ to work with the /etc/shadow file in Linux. If I manually paste the DES encrypted password from the /etc/shadow file into the /etc/tac.conf file (using the line "login = des <encrypted_passwd>"), then I can successfully authenticate using my Linux user/pass combo. However, when I change the tac.conf line to "login = file /etc/shadow", it doesn't allow me to authenticate with the same password.

Am I doing something wrong? Do I need to uninstall tac_plus and recompile it? I read something about modifying the pw.c file in the source code directory and having to recompile the software. I tried this, but I am relatively novice at things Linux, and I'm not exactly sure whether or not I need to somehow uninstall the program before recompiling it, or even how to recompile it for that matter.

Any help will be appreciated!

Re: TACACS+ and /etc/shadow

When it is working when manually copied, it should work; may be you can try uninstalling tac_plus and recompiling it.
