I tried the beta LDAP integration for Vikunja, however, our LDAP provider requires anonymous binds for looking up the initial user tree. I tried using empty strings for username and password but this is not recognised as anonymous.
There seems to be an option using Go LDAP (Golang Ldap Authentication, Bind and Search, including Anonymous Bind · GitHub) for anonymous bind using UnauthenticatedBind. Would this be an option for Vikunja?
Happy to merge a PR implementing this.
