The London Perl and Raku Workshop takes place on 26th Oct 2024. If your company depends on Perl, please consider sponsoring and/or attending.


Auth::Krb5Afs - get Krb5 and OpenAFS tokens


 use Auth::Krb5Afs;
 my ($err, $pwent) = Auth::Krb5Afs->authenticate($user, $pass);


invokes kinit and aklog to get Kerberos 5 and OpenAFS tickets


$auth = Auth::Krb5Afs->new();

Create a new instance. You could also use Auth::Krb5Afs->authenticate() without an instance variable.

($err, $pwent) = $auth->authenticate($user, $pass);

invokes "kinit" and "aklog" to get krb5 and afs tokens. By default, the krb5 ticket is good for 20 minutes, renewable up to 10 hours.

If successful, sets the USER, HOME, and SHELL environment variables, the current uid and gid, and chdirs to HOME.

In an array context, returns an array ref to the result from getpwuid($afs_uid).

In a scalar context, returns error strings in a hash like $err->{pass} = "unknown user or wrong password";


The bin/authkrb5afs program behaves like one of courier's authlib modules. It reads password etc from file descriptor 3, then invokes the rest of its command line as the user.
