Problem Description

When logging in with Kerberos error messages on token validity show up which differ dependent on using url or explicit parametrization. App is then non-functional. Despite error message embedded MongoDB shell seems to work. Issuing a valid command through shell and refreshing the data makes the app behalf normally.

Steps to Reproduce

When logging from New Connection screen with url

mongodb://<user>%40<REALM>:@mongodb:27017/?gssapiServiceName=mongodb&authMechanism=GSSAPI&readPreference=primary&authSource=%24external&appname=MongoDB%20Compass&ssl=false

it shows "AcquireCredentialsHandle: The token supplied to the function is invalid"

When then switching to "Fill in connection fields" and connect from there the

screen switches to normal view with error message "An error occurred while loading navigation: InitializeSecurityContext: The token supplied to the function is invalid" on top.

However, MongoSH Beta at the botton is in fact connected.

View -> reload data

has not effect

Issuing a valid command in MongoSH and after that retrying

View -> reload data

populated the upper part of the screen and the app works as expected from then on. 

Expected Results

login via url or parameters should behave the same

login with valid Kerberos credentials should work

Actual Results

login via url or parameters behaves different

login with valid Kerberos credentials does only work on embedded shell

Additional Notes

I verified the correct Kerberos setup on server side with a mongosh connection from a Linux machine using GSSAPI. Also server log indicates that GSSAPI handshake with compass did complete.
