[pbs-devel] [PATCH proxmox 1/4] ldap: remove support for unauthenticated binds

[Stefan Sterz <s.sterz@proxmox.com>]

by using the default empty string if no password was provided,
unauthenticated binds were possible. to bring pbs in-line with pve,
switch to throwing an error in this case instead. however, this will
break any pre-existing setup that relied on this behavior.
