Can't create user #739

DebenOldert · 2012-12-05T23:14:37Z

When i try to add an user i get an popup that says: can't create user. User already exist.
But the user doesn't exist.

ako84 · 2012-12-17T20:56:12Z

i have the same problem. When i create a user a popup apperas with the message "cant create user. User already exists"
i tried different usernames, which dont exist. At the moment my owncloud has 20 users and some groups

there are no errors listed in the owncloud log file and no ones at the apache error log.

i am using owncloud 4.5.4

What do the user names look like?
Any non ascii characters?

ako84 · 2012-12-18T09:44:52Z

for example:
username: name
passw: 12345

Any error in the browser's javascript console?
Which browser on which OS are you using? THX

DebenOldert · 2012-12-18T10:01:54Z

I fixed it!
I reinstalled windows and reinstalled owncloud.
Everything works fine now.
My OS windows and mac
Both didn't work
I used different browsers ( safari, chrome, internet explorer) and these didn't work too.

hm...sure? i could only see contents at warnings and errors...
but not at normal network requests without errors.

how do you get the content at chrome?
i am not familiar with that

tanghus · 2012-12-18T19:42:24Z

In Chrome press F12 to get to Developer tools. Select the Network tab, try to create a user and then click on the entry for createuser.php

ako84 · 2012-12-18T21:52:16Z

ok i installed chrome

i have two path to select:
createuser.php
delete.png

createuser.php (i changed the host IP to 00.000...for safety):

one more info:

it seems, i configurated my owncloud using SQLite not MySQL during install. I opened owncloud.db from the data directory. The database contains only the 20 existing users.
i have access to the data directory only as root. i hope this is correct...

slonkak · 2012-12-19T14:10:18Z

I have the same problem. I recently updated my install from 4.5.3 to 4.5.4 following the procedure on owncloud's site. Before hitting the URL again I copied back the config.php file and everything instantly worked. I was able to add users. Now, all of a sudden, I can no longer add users with the same error as the OP. I am using MySQL as the backend and have 23 users.

I've read that people have deleted config.php and let owncloud regenerate it, but I'm afraid of doing that in case it tries to wipe my data dir (which contains TBs of data) or wipe my user accounts. If someone can guarantee that deleting config.php and re-setting up owncloud will not destroy any existing data I'll do that and see if it helps.

ako84 · 2012-12-19T16:21:54Z

hi

i deleted config.php and regenerated it. After that, a white screen appears if i logged in...
Now i copy back my backup.

Befor updating my owncloud from 4.5.3 to 4.5.4 adding new users works fine...

RandolfCarter · 2013-01-19T10:01:43Z

As stated in #1209 already: This is most probably a problem with an authentication app (e.g. webdavauth) being enabled - when the user backend can't search for a user (only authenticate it), these apps return "exists" for every username, therefore preventing creation - what would be nice would be a more fitting message (e.g. "User backend xyz prevents creation of new users").

karlitschek · 2013-02-09T09:37:45Z

@DeepDiver1975 Is this fixed with you latest changes?

ako84 · 2013-02-09T10:15:01Z

no, i still cant create users. Only directly in the MySQL database...

EDIT: i can create users, if webdav user backend is disabled! (like RandolfCarter wrote above)

DeepDiver1975 · 2013-02-09T13:15:48Z

no yet - blocked by another pr at the moment

DeepDiver1975 · 2013-03-07T09:35:47Z

@DebenOldert @ako84 Does this problem persist with the latest 4.5.7? THX

ako84 · 2013-03-07T10:36:43Z

yes, the problem still persists. But only with enabled webdav user backend.

DeepDiver1975 · 2013-03-07T10:41:36Z

Okay - this is an acceptable solution to the issue.
It has been fixed with OC5
The required change to make it work in 4.5.x would possible break to much -> closing.

THX a lot!

zeigerpuppy · 2014-05-04T07:04:22Z

Looks like this bug is back on 6.0.3. I have enabled IMAP logins using the following code in config.php.
IMAP user logins work fine but when I try to create a normal owncloud user, it fails with the error:
"Can't create user. User already exists."

It's pretty clear that this is replacing rather than augmenting the user backend. Is there a way to use both backends?
Is installing the plugin at https://github.com/DSI-Universite-Rennes2/user_imap a better way to achieve IMAP logins?

require_once(dirname(__FILE__).'/../apps/user_external/lib/imap.php');
...
"user_backends" => array (
    0 => array (
            "class"     => "OC_User_IMAP",
            "arguments" => array (
                              0 => '{mail.localnet/novalidate-cert:143}'
