I just want to know if it's possible to customize the forms to add/modify users in OTRS. I have users stored in an external DB (for an ERP) and as I have to make some interfaces between OTRS and ERP I want to store the IDs of the ERP users in OTRS.
I already add a field in the table "users" and I tried to modify "AdminUserForm.dtl" but without success... I'm not sure if it's the correct file to change

And my problem is : how can I make the link between dtl file and the DB? If I can change the dtl file to add a new field, how it will be taken in the SQL update ?
Thanks for your replies!
