Failure to correctly set display names to First/Last Name

Troubleshooting
2

hi @klaatu, welcome to the community!

Based on your description, this appears to be a potential bug in the software. Would you be open to help share the following, so we can more easily troubleshoot it:

  1. What OS and version is the Mattermost server installed? (E.g.: Ubuntu 16.04, RHEL 7.1)
  2. Are you running Mattermost in a container and/or using container orchestration?
  3. Are multiple people experiencing the same issue after you try to change the default to First/Last name, including a newly created account?
  4. Can you help confirm you are changing the setting in System Console > Users and Teams > Teammate Name Display?

As for the nickname attribute - this may be related to how the nickname field is defined in the database (set to a max of 22 characters by default). We can verify this.

For your users, if they can set the First and Last names to long strings, is there a different field they’d like to use for the nickname that is equally as long?
