Bug description

WebDAV access is not working with FreeIPA LDAP backend with OTP. More precisely, the password has an OTP token as suffix, which means there is a single password but constantly changing. It seems to be related to these issues: #11113
nextcloud/documentation#9726

I can confirm 'auth.storeCryptedPassword' => false is fixing the logout issue every 5 min, but WebDAV access is still not working at all. It is completely impossible to connect. After disabling OTP everything is fine.

Steps to reproduce

1. Enable OTP in FreeIPA
2. Try to connect via WebDAV (davs://<hostname>/remote.php/dav/files/<username>)
3. Getting authentication failure

Expected behavior

If the OTP is currently valid, authentication should be successful.

Hi @duburcqa - Are you still experiencing this?

[nextcloud-command]

This issue has been automatically marked as stale because it has not had recent activity and seems to be missing some essential information. It will be closed if no further activity occurs. Thank you for your contributions.

The issue has been fixed ? On my side, I’m not planning to use OTP anymore due to a collection of issues like this with our whole tool suite and not enough benefits, so i cannot tell you whether it is not buggy or not.
