Hi there
Same issue here, although running another Zammad version (5.4.1).
I found a workaround for this. You can define the mappings in the Zammad Rails Console like this:
Open console with
zammad run rails c
# First get a list of role id/name
Role.order(:id).pluck(:id, :name)
Adjust the LDAP configuration with
# Load config
l = LdapSource.first
# List current group role mapping (should be empty now)
l.preferences["group_role_map"]
# Configure the mapping (adjust group dn and role id to your needs)
l.preferences["group_role_map"] = { "cn=groupname,ou=groups,dc=..." => ["3"] }
# Save configuration
l.save
You can define as many group <> role maps as you need.
Hope this helps until the editing in the GUI is fixed.
Regards,
Patrick
