Can't authenticate into the SudoSpawner hub

[harschware]

When I attempt to use sudospawner at http://localhost:8001, I get to the spawner options page and enter the password for the alice user 'alice'. I get the error below. Should I be entering "alice" in this form? sorry new to kerberos and fumbling through...

Was this erroring occurring before you pinned versions? For the record, you should be entering username: alice, password: alice as you said.

no, it occurred after.. I do recall my system was just a bit slow at the time. I retested just now and the error no longer occurs. I've noticed that, even with my 2016 Macbook Pro in fairly idle state authenticating into the hubsudo_1 takes on the order of about 20 seconds. I'm thinking that at the time because my system was limping a little that I just was legitimately hitting the 30 second timeout. Is that a configurable parameter? I wonder why the authentication process is slow?
