@boldandbusted Did the user ever logged in after the user was added and encryption was enabled?

Hello,
@MorrisJobke I'm having the same problem on Nextcloud 10 beta. I never activated encryption. The password reset feature is renderd useless by this misbehaviour

[jgrete]

Hi,
the same problem with 10 RC1 !
No solution?

I have the same problem on stable9 and it seems on webdav calls from the sync client 2.2.3.
Need to check further whether the web access also causes this.

Hello,

I had the same error message, after I had activated the Addon for the encryption. And would login with a another user account (no Admin).
For this user a private & public key had been (before the activation of the Addon) already exist.

Solution: i delete or rename both keys, and login again
sudo rm /nextcloud/data/USER/files_external/rootcerts.crt
sudo rm /nextcloud/data/USER/files_encryption/OC_DEFAULT_MODULE/USER.privateKey
sudo rm /nextcloud/data/USER/files_encryption/OC_DEFAULT_MODULE/USER.publicKey

@MorrisJobke Nope. Still the same issue, now with NextCloud 10.0.1. UPDATE: Raiko's fix fixed it, but what a hack. :)

[schiessle]

I'm aware if this issue. The Problem is that the keys still exists but of course Nextcloud can no longer decrypt the private key. The idea was that password should give you a basic access to your Nextcloud, e.g. to access your calendar and contacts again but at the same time keep the old keys in case a admin can later recover the users files.

Of course there is also the case where no way to recover the files, if no revovery key is enabled and if the user has no chance to get back the old password. Probably a new UI/OCC command like suggested in #2908 would be needed. I will have a look and suggest a solution.

[djermann]

I have the same problem. It first showed up on version 9.0.51 and it is still there in the newest version 11. The password actually resets, but the error message still pops up. I am using nginx, postgreSQL, debian 8.6, php 5.6.29.
I would be happy if someone could solve this problem, because I have a lot of customers that are contacting me because of this.

[zecke]

Maybe a missing openssl.cnf, e.g. like in #2907?

[djermann]

I do have an openssl.cnf file in /etc/ssl/ . Is this the one you are talking about?
