Additional info

Everything was working since Nextcloud 21, doing upgrades carefully and updating the Nginx example configuration file each time. I'm not sure if it's a desktop (nextcloud/desktop#6204) or a server bug in the end...

This is coming from the password_policy app but it's barely changed lately (managed via Admin settings->Security):

password_policy/lib/Compliance/Expiration.php

Line 92 in 8e31a74

$message = 'Password is expired, please use forgot password method to reset';

For completeness can you provide the output of:

occ config:list password_policy

(Or equivalent)

It's notable it is only impacting your client app connections and not web.

What version of NC, specifically, were you using immediately before this behavior started / before this most recent upgrade?

Hello,

Thank you very much for your answer. Please find my responses below:

For completeness can you provide the output of:

occ config:list password_policy

(Or equivalent)

$ php8.2 --define apc.enable_cli=1 occ config:list password_policy
{
    "apps": {
        "password_policy": {
            "enabled": "yes",
            "types": "authentication",
            "enforceUpperLowerCase": "1",
            "enforceSpecialCharacters": "1",
            "historySize": "10",
            "enforceNumericCharacters": "1",
            "minLength": "8",
            "installed_version": "1.17.0",
            "expiration": "365"
        }
    }
}

It's notable it is only impacting your client app connections and not web.

I'm sorry, I'm not sure I understand what you mean by that. Is it the expected behaviour that client application connections are causing issues but not the web?

We were using v27.1.2.1.

Thanks again!

        "expiration": "365"

Are you sure the password isn't just expired?

Are there many users on this server? Can you provide the output of ./occ user:setting <username> password_policy for one of your users?

Redact anything you consider confidential.

Not expected. A clue maybe.

Hello!

Are you sure the password isn't just expired?

Why would it have expired if all accounts are still able to login to the web interface?

Are there many users on this server? Can you provide the output of ./occ user:setting <username> password_policy for one of your users?

There are a little over 100 users on the server, none can connect with a client which isn't the web interface.

See the output of the command below:

$ php8.2 --define apc.enable_cli=1 occ user:setting REDACTED password_policy
  - password_policy:
    - failedLoginAttempts: 0
    - pwd_last_updated: 1667198578
  - settings:
    - display_name: REDACTED

Considering the UNIX timestamp value printed here, the password seemed to indeed have expired on Mon Oct 31 2022 07:42:58 GMT+0100 (Central European Standard Time). However, that doesn't explain why everyone is still able to login on the web interface. Looks like a bug?

Okay, thanks again for your help!

However, that doesn't explain why everyone is still able to login on the web interface. Looks like a bug?

Might be a bug indeed. And the timing may just be a coincidence - may have nothing to do with v27.1.2->v27.1.3.

My best guess is a difference between:

• Logins via Cookie
• Session renewal
• Something with app passwords

We'll have to look closer.

For your information it's still happening. The "Forgot my password" to rotate the password works as expected but this still looks like a serious security issue if you can still login in the web UI while your password has expired.

Did you mean to close your report? I reopened it since it seems like something that still needs to be addressed.
