Cannot change username with SSO enabled

(Felix Freiberger) #1

When renaming a user (from jb1 to jb), I get this error message:
There was an error changing your username.

No information is recorded in /logs.
The old username was created because the user used SSO for the first time, and his name was too short. Now, I changed the minimum username length, and wanted to adjust his name.

what happens when you rename to jb2 … jx ?

(Jeff Atwood) #3

Almost certainly a length restriction. Unlikely to be a bug.

(Felix Freiberger) #4

Is there any setting for length restrictions apart from min username length, which I have set to 2?
Setting any other name does not work either.

(Jeff Atwood) #5

Changing username minimum after the fact (e.g. setting minimum username length to 4 chars, when you have ten users with 2 char usernames) will cause lots of problems.

(Sam Saffron) #6

what happens if you restart your container, maybe something bad is cached?

(Felix Freiberger) #7

I restarted (or in fact: rebuild) the container, this did not help.

I found it: sso overrides username prevents the name change.

I still consider this situation a bug. Enabling this setting should either hide the Change Username button from the administrator panel and disable the users/.../preferences/username page, or still allow username changes for admins (possibly with a warning).
I’d prefer the latter, to allow admins to manually “untangle” cases where Discourse’s change-illegal-names-system has created unintended names.
