I have been having problems with kerberos since going to 1.5 as well, on
my system i cant figure out how to make it *not* try and authenticate with
kerberos... so login/su/etc all try to find a krb realm and block for a
few seconds while they wait for the gethostbyname to timeout. I sent a pr
about this and recieved no response, does anyone know how to fix it?
