Can you activate LDAP post-installation or would I have to re-install?
Exactly what I'm thinking... I'll go and see...

@jdaviescoates I’ve updated one of my wp apps, installed the ldap plugin used the managed ldap settings and (just to be sure) after a restart of the app ldap works!

Aha, I also just updated and didn't see any LDAP support, but this is the step I'm missing!
@girish be nice if updating Unmanaged to the new Developer version auto-magically installed the LDAP plugin and settings!

When you go to Access Control in your updated app are you now seeing this? (as per how it looks if you install and choose LDAP on install)

I would have missed that necessary step myself. The only reason I didn't check on my own install is because @girish made a "hot fix" for me for my development and I had a VM issue so I re-installed and was refusing to go through the setup because I was afraid cloudron-machine wouldn't work after setup. But @girish confirmed today it does work after setup so I'm going to have fun testing out this LDAP integration with WP and figure out how
cloudron-machineworks later. -
@jdaviescoates What @imc67 did should not be possible, so I am not sure how it works for him. The LDAP will only be available for new installations since this flag is chosen at install time and there is no way to change it post installation without tinkering with the database. Might be easier to export/import into a new install. Just backup current app, make a new LDAP based install and import that backup into new app.

Oh, gotcha, it can only be set at install time. So, do you think your suggestion to "set the flag without DB voodoo" (which I'm gonna do because I can't get the cloudron app db to work with remote sql, I've tried a lot). Do you think that method will clash with multisite database URL location changes (Wordpress storing the URL in a different place than single site)?

@imc67 Ah yes, I see why it works.
From a security perspective, each app gets it's own addon credentials (database, redis, ldap etc). When app is installed/uninstalled, we create/destroy a separate username/password/database for each app. Now, Cloudron could have gone a step further and implemented a security measure that these credentials will work only when the specific app uses it. This can be done because each app has it's own IP address internally (via Docker). We haven't implemented this, and as a result, the credentials of one app (say mysql username/password/database) can be copied over to another app and it will work. But it will only work until the other app exists. When the other app is uninstalled or repaired/restored etc, the credentials are regenerated.
In the case of LDAP addon, there is a so called "bind" password which allows apps to make LDAP queries. We generate a bind password per app. However, currently, we don't enforce this password since some apps do not support it. This WordPress LDAP plugin we use is one such case (probably one of the remaining 3-4 apps in Cloudron). Because, it doesn't use a bind username/password, all you are copying over is the LDAP server credentials (server name/port which is the same across all cloudrons). So, this happens to work now. But later when we fix the plugin to use LDAP credentials, it will stop working.
Also, you will see inconsistency in the UI since Cloudron is not aware that LDAP is enabled for the app. You will see a different access control view than what @jdaviescoates posted. You also can't control which users have access to ldap from the Cloudron UI. In fact, I am going to guess only admins can access your WP install (since they are allowed by default).

Where might I be able to find this bind password? I made up my own tiny PHP library for LDAP in the VPN Client and I did not use a bind password even though it's not required "for now". So, I would def like to fix that preemptively.
But later when we fix the plugin to use LDAP credentials, it will stop working.
Did you write this pugin yourself or do you need to make the fix upstream with another team?

@girish that's sad, as the expectations with "upgrading" the app to 'developer' suggested all the long awaited new functionality.
Yeah. For LDAP, we don't have a mechanism to easily to turn it on/off dynamically ie after an app installed. Let me discuss this with @nebulon to see if this is something we should do for Cloudron 6 because it's easy to do on Cloudron side (but we have to test with all the apps to check how well they cope).
If it's urgent, the easiest way is to just:
- Backup current app. Download the backup config
- Make a new install of WordPress (Developer), you can keep the existing app running.
- Then import the backup config into this new app. App -> Backups -> Import. Upload the config from step 1.
- Login to WP of the new app and install authLdap plugin. After doing so, Restart WordPress. Cloudron will configure the LDAP plugin on restart.
- If all looks good, you can switch the location

It's authLdap. We have contributed patches in the past like this one. So, have to invest more time into adding bind password support.
