Deal with names in Zulip
Currently, it's possible to change your "full name" in Zulip, even though this is originally taken from Stackspin when the user first logs in.
This presents us with a bit of a problem, now that we're provisioning users via SCIM: the dashboard will override any modifications to the name in Zulip with the value from Stackspin.
We should probably:
- Try to disable changing the full name in Zulip from now on. There is a setting for that. We'd have to check that changing it via SCIM is then still possible.
- Send out a message to the customers explaining the situation and advising them to change their "display name" in Stackspin if they want to set it (again). Maybe also mention that Zulip has special pronoun support which can be used instead of adding the pronouns to the name as people now sometimes do.
We can also try if it's possible to not include the full name in the SCIM call to Zulip (POST and/or PUT), in particular when the full name is not set in Stackspin.
