Patch to add RPC authentication support over PAM

[andrew.sichevoi]

Hello there,

I have added RPC authentication support for transmission daemon over PAM (Pluggable Authentication Modules subsystem). Please consider adding the implemented feature to the trunk/. So user can connect to its transmission-daemon instance using his/her system credentials.

Patch brief: added native user authentication for transmission-daemon. Currently Linux only.

Version to apply: trunk@13057

Notes:

• The main reason for me for this feature was an ability to maintain easily access for running transmission daemon.

• PAM authentication is enabled through rpc-native-authentication-enabled cfg keyword. It was called 'native-authentication' since for other OS`s the ways to authenticate user differ from PAM.

• To make PAM authentication work correctly, transmission-daemon instance must be added to 'shadow' group to be able read '/etc/shadow' file if authentication is made over pam_unix.so

Benefits:

• Easy maintain user access to transmission-daemon

• Transparent authentication: thanks to PAM configurability authentication can be performed even via LDAP (as example).

Thanks very much for the patches; they look good.

However, this is not a feature that anyone else has ever asked for. I'm hesitant to add more code -- even free, good code -- for a feature that doesn't appear to have many potential users.

jordan: could you make a wiki page to collect this patches? It would be good, if someone need a feature - but you dont want to include to T -, they can easy search them.
