Proxmox does not allow the prefix x- to be used as an LDAP object class name.

> Names should be registered with the IANA or prefixed with "x-" to place in the "private use" name space.

As mentioned above, user-defined LDAP object classes and attributes must be prefixed with x-.
Despite this requirement, if you use an LDAP server for user management in Proxmox, the prefix x- is not accepted. (See attached image)

Are there any plans to fix this specification?

Hi,

you may want to report this in our bugtracker: https://bugzilla.proxmox.com/
There it can be tracked properly - the fix should be relatively simple.

I will report this there.
Thank you.
