Allow LDAP access for Webserver app

[mrmarkuz]

When installing a site using LDAP on the Webserver app, the ldapproxy isn't reachable. As a lot of web apps use LDAP we should allow it.

Proposed solution

Add --network=slirp4netns:allow_host_loopback=true to the webserver service to allow LDAP access.

Alternative solutions

Use the custom configuration as explained in the community

Thanks to kovand for proposing this feature.

for the record, this could be done manually by creating a systemd template service, in the meanwhile there are a lot of cases where the web application could need to connect to a LDAP server, but sometimes not on the cluster

what do you think @DavidePrincipi

won't fix for now, we can add it manually by a systemd service
