When I say the auth-passthru instructions are not very clear what I mostly mean is the bit that says: You create an osTicket user / staff account by typing in the username
from the AD/LDAP user in the field "username" - in osTicket should now
appear a dropdown list with all usernames matching the search of ldap
users - select the username you like to add and the info like "username"
"firstname" "lastname" etc. should be pulled automatically from ldap.
As auth backend select "any backend".where is the field username? where is the dropdown in osTicket?
