[FEATURE] Support sourcing User-Email from a LDAP user attribute #699
Description
Is your feature request related to a problem? Please describe.
Now with added LDAP groups support I am considering adding Tinyauth to my auth stack as a auth_request handler. I'd like to use the Headers feature with my existing LDAP instance, as I asked in #692.
Describe the solution you'd like
Add support for sourcing the header data from LDAP. Maybe even add LDAP support to custom headers?
Describe alternatives you've considered
Not using Tinyauth/not using headers? idk
Additional context
I may give adding the feature in myself a try during the coming weeks if i have the time. Great project btw keep up the good work!
