# sfsauthd(8)

SFS authentication daemon

## NAME

sfsauthd - SFS authentication daemon

## SYNOPSIS

/usr/local/lib/sfs-0.8pre/sfsauthd \[-u *sockfile*\] \[-f *config-file*\]

## DESCRIPTION

**sfsauthd** is the program responsible for authenticating users.  **sfsrwsd** and other daemons communicate with **sfsauthd**, forwarding it authentication requests from **sfsagent** processes on remote client machines. **sfsauthd** informs requesting daemons of whether authentication requests are valid, and if so what local credentials to associate with the remote user agent.  The **sfskey** program also communicates directly with remote **sfsauthd** processes when retrieving and updating users keys (with **sfskey add**, **update**, **register**, and more).

## OPTIONS

- \-f *config-file*

  Specify an alternate **sfssauthd\_config** configuration file.  The default, if **-f** is unspecified, is */etc/sfs/sfsauthd\_config*.

- \-u *path*

  Bind unix domain socket *path*, and accept TCP connections passed over connections to that socket.  This option allows **sfssd** to communicate with already running **sfsauthd** commands using a directive like **Service 2 -u** *path* in *sfssd\_config* .

## FILES

- */etc/sfs/sfsauthd\_config*

  - */usr/local/share/sfs/sfsauthd\_config*

  user-authentication daemon configuration

(Files in */etc/sfs* supersede default versions in */usr/local/share/sfs*.)
