Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can 
Nextcloud version (eg, 12.0.2): 17.0.2
Operating system and version (eg, Ubuntu 17.04): ubuntu-server 18.04.3
Apache or nginx version (eg, Apache 2.4.25): NGinx version 1.17.4
PHP version (eg, 7.1): 7.3.13
The issue you are facing: After update (successful) from 16.x to 17.0.2 i tested first with nc admin account. All well so far - at first - but today i wanted to change something in my user-account (an LDAP User - AD member) and that second i click on settings my cloud webui switched over to files.
I reproduced this several times - in log files no entry.
I tested with another user account but with local authentication - no problem.
I switched back again to admin account (local password) and double checked my LDAP/AD settings
All was tagged ok (Connection established, all good …)
I listed my users - alls well so far.
And back again to my user account with ldap credentials. Loged in properly but no admittance to enter the settings page. No error message, no logs - just pulled me back to files section every time i click to enter my settings page.
Is this the first time you’ve seen this error? (Y/N): Y
Steps to replicate it:
- update 16 to 17
- create ldap account
- make test
- take a click on settings page

The output of your Apache/nginx/system log in /var/log/____:
Dec 22 15:08:23 server systemd[1]: Starting Clean php session files...
Dec 22 15:08:23 server sessionclean[2148]: find: ‘/usr/local/tmp/sessions/sess_hash-value’ kann nicht gelöscht werden.: Das Dateisystem ist nur lesbar
I get many of these messages above - but no log entry for login failure. It is in my opinion no login failure itself because users can login - but after that are not able to enter their settings page.
For testing i deleted all sessions in /usr/local/tmp and loged in back again with no change.
I tried with safari browser instead of mozilla - no change.
I am not sure but the error occurs since update to 17.x version and in the change log i’ve read that since 17th version of Nextcloud there where changes concerning ldap / password etc.
That’s the reason why i’ve double checked my LDAP settings with admin account after remarking the error.
