Username Not Accepted for Login But Email Address Is?

System Info: Latest Version of OwnCloud on ESXi Debian Server with OwnCloud in Docker Container.

Even though the login/credentials area indicates that a username or email address is acceptable for login purposes; however, on my OwnCloud, only email address work. Am I missing something?

Thank you.

Actual behaviour

Tell us what happens instead

Server configuration

Operating system:

Web server:


PHP version:

ownCloud version: (see ownCloud admin page)

Updated from an older ownCloud or fresh install:

Where did you install ownCloud from:

Signing status (ownCloud 9.0 and above):

Login as admin user into your ownCloud and access 
paste the results into and puth the link here.

The content of config/config.php:

Log in to the web-UI with an administrator account and click on
'admin' -> 'Generate Config Report' -> 'Download ownCloud config report'
This report includes the config.php settings, the list of activated apps
and other details in a well sanitized form.


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

*ATTENTION:* Do not post your config.php file in public as is. Please use one of the above
methods whenever possible. Both, the generated reports from the web-ui and from occ config:list
consistently remove sensitive data. You still may want to review the report before sending.
If done manually then it is critical for your own privacy to dilligently
remove *all* host names, passwords, usernames, salts and other credentials before posting.
You should assume that attackers find such information and will use them against your systems.

List of activated apps:

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

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)

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

Good Lord! That’s lot of detail when I was simply asking if anyone else had bumped into the problem.

I (partially) agree. I like to help wherever I can, but not guessing into the blue. Or asking simple config questions over and over again.

Au contraire, You did not ask if anyone else had bumped into the problem, your question was “Am I missing something?”

I’m pretty sure there are exceptions in your owncloud.log, which you decided not to provide. Additionally you did not write any information about your setup. So where should we start?

I never met this issue, if this is your only question.


I just love forums. Asking for such a level of detail for a simple question is overreaching. Why would I or anyone go to that much effort if it was a simple setting I had missed? I didn’t declare it as a “bug”, I simply asked did I miss something as in setup, had I missed seeing it listed as a known problem, and by inference, had I missed it somewhere that anyone else bumped into it.

Having used ownCloud for less than a week, I’m not sure I would even know where to provide that level of detail nor would be so inclined for such a simple, casual question. I openly said “have I missed something?” No criticism of ownCloud was made nor implied. I have asked other questions in this forum and not been challenged to provide such a level of detail for far great complexities. If I were on the other side of the fence, if I were “ownCloud”, I would first ask how often has someone noted this before I go gathering tons of details and trying to analyze it. So I gather that no one has experienced this problem. Okay, I’m good with that. Thank you for your time.
