OC_USER_IMAP Backend after update to 3.4.0 NC13

[fl0w1]

Hey,

after the last update to version 3.4.0 users with oc_user_imap backend cannot
longer login. Right after logging in the Nextcloud 13 Server responds with internal Server Error.

Server details:
Nextcloud 13.0.2
JavaScript XMPP Chat 3.4.0
Browser: Multiple Browsers tested (with and without addons)

Error Message from NextCloud Log:
{"reqId":"WwfEbMtviJtFPDPNTeikpAAAAFI","level":3,"time":"2018-05-25T10:08:13+02:00","remoteAddr":"","user":"[email protected]","app":"index","method":"GET","url":"/","message":"Exception: {"Exception":"Error","Message":"Call to undefined method OC_User_IMAP::getBackendName()","Code":0,"Trace":"#0 \/var\/www\/nextcloud\/html\/apps\/ojsxc\/appinfo\/application.php(284): OCA\\OJSXC\\AppInfo\\Application::convertToRealUID('user...')\n#1 \/var\/www\/nextcloud\/html\/apps\/ojsxc\/appinfo\/routes.php(8): OCA\\OJSXC\\AppInfo\\Application->__construct()\n#2 \/var\/www\/nextcloud\/html\/lib\/private\/Route\/Router.php(351): include_once('\/var\/www\/cloud....')\n#3 \/var\/www\/nextcloud\/html\/lib\/private\/Route\/Router.php(151): OC\\Route\\Router->requireRouteFile('\/var\/www\/cloud....', 'ojsxc')\n#4 \/var\/www\/nextcloud\/html\/lib\/private\/Route\/Router.php(268): OC\\Route\\Router->loadRoutes()\n#5 \/var\/www\/nextcloud\/html\/lib\/base.php(999): OC\\Route\\Router->match('')\n#6 \/var\/www\/nextcloud\/html\/index.php(37): OC::handleRequest()\n#7 {main}","File":"\/var\/www\/nextcloud\/html\/apps\/ojsxc\/appinfo\/application.php","Line":366}","userAgent":"Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:61.0) Gecko/20100101 Firefox/61.0","version":"13.0.2.1"}

The problem was solved by disabling the ojsxc app.

Cheers,

Do you use the internal chat backend?

[fl0w1]

Yes, I do.

[sualko]

Can you test the above patch?

According to my sources ;-), every call of getBackendName in Nextcloud itself looks like that:

• https://github.com/nextcloud/server/blob/master/lib/private/User/Manager.php#L371
• https://github.com/nextcloud/server/blob/master/apps/files_versions/lib/Command/CleanUp.php#L79
• …

The patch works for me, with the IMAP backend. Thanks.
