I believe the snippet pasted by Weijun comes from here:
https://web.mit.edu/kerberos/krb5-latest/doc/admin/conf_files/krb5_conf.html
[ search for auth_to_local ]
however for 1.17 version the same paragraph uses format as follows
[realms]
ATHENA.MIT.EDU = {
auth_to_local = RULE:[2:$1](johndoe)s/^.*$/guest/
auth_to_local = RULE:[2:$1;$2](^.*;admin$)s/;admin$//
auth_to_local = RULE:[2:$2](^.*;root)s/^.*$/root/
auth_to_local = DEFAULT
}
So it looks like the krb5-latest doc is kind of confusing.
