Glad you got it worked out. FWIW, I tested the auto-create setup and it did work -- user is not in Guacamole DB, authenticates against LDAP (AD) and is created in Guacamole DB (you still have to go assign a group or connection afterward, per the docs).
You do have to make sure you set: mysql-user-required: false if you set: mysql-auto-create-accounts: true On Fri, Jan 14, 2022 at 10:09 AM Jim Rx <jimr...@mail.com> wrote: > Johnathan, > > I was over-complicating things.
