Can't rename users full name - Authentication error

[camoflash]

Steps to reproduce

0. Open any browser, log into nextcloud as an Administrator and go to page where you can edit all users
1. Open browser's Inspector tool -> Network tab
2. Edit user's 'Full Name' field
3. Look for POST Request named displayName in Inspector tool
4. Look at the POST Request response
5. Reload page to see if 'Full Name' field is changed

Expected behaviour

• Dialog box asking for password confirmation before changes to user's 'Full Name' field is commited
• POST Request "displayName" getting a good response
• Reloading page should have shown changes to user's 'Full Name' field

Actual behaviour

Tell us what happens instead

• No password confirmation dialog appearing
• POST Request is returning the response: {"status":"error","data":{"message":"Authentication error"}}
• Reloading page does not show any change to user's 'Full Name' field

Config report

If you have access to your command line run e.g.:
sudo -u www-data php occ config:list system
from within your Nextcloud installation folder

or 

Insert your config.php content here. 
Make sure to remove all sensitive content such as passwords. (e.g. database password, passwordsalt, secret, smtp password, …)

Are you using external storage, if yes which one: local/smb/sftp/...

Are you using encryption: yes/no

Are you using an external user-backend, if yes which one: LDAP/ActiveDirectory/Webdav/...

LDAP configuration (delete this part if not used)

LDAP config

With access to your command line run e.g.:
sudo -u www-data php occ ldap:show-config
from within your Nextcloud installation folder

Without access to your command line download the data/owncloud.db to your local
computer or access your SQL server remotely and run the select query:
SELECT * FROM `oc_appconfig` WHERE `appid` = 'user_ldap';


Eventually replace sensitive data as the name/IP-address of your LDAP server or groups.

Can not reproduce on 14.0.0 RC 2 so i would assume it has been fixed since then.
Will try to find the fix so it can be backported.

Edit:
I did not know that the entire js stuff was rewritten.
Will leave this to someone that is more familiar with the codebase.

Not likely to be back ported as we moved to a completely new code basis. Sorry for that. I would close this for now.

If you have still problems: could you try the provisioning API to update the display name and check also the logs for suspicious entries? We then can reopen the issue.
