How to prevent FreeRADIUS to send Access-Reject if Username not found

8 Apr 2019

      Hello, dear community!
I am struggeling on prevent freeradius to send a access-reject if the user does not exist in the LDAP-Database.

I did already query if user exist or not and send reply-message “uid not found” but instead I want to send absolutely nothing.
But I get Access-Reject because ldap can’t find the uid and set Auth-Type to nothing, so freeradius say  “ERROR: No Auth-Type found: rejecting the user via Post-Auth-Type = Reject”
Is there any way to tell freeradius to send no reject if user not found? Only if authentication fail because of invalid password, not non-existing username?

Here is some debug output from FreeRADIUS (I replaced my domain and ip address from the output)
