Hello Antonio,
I think the problem is that you have specified that the SQL nthash is to be
used as Encrypted-Password, but you have prefixed it with {nthash} as if it
were to be used as User-Password. If the passwords have {nthash} in front,
you should use User-Password like this:
AuthColumnDef 0, User-Password, check
Encryted-Pasword should only be used if there is no other indication that the
password is encrypted.
Actually I would think it would be better if you had:
AuthSelect SELECT NTLM,\
CONCAT(User,'@',Domain) AS Username, VLAN FROM users where\
CONCAT(User,'@',Domain)='%n' AND AccWiFi='1'
AuthColumnDef 0, Encrypted-Password, check
and use the NTLM hash directly?
Your choice.
Cheers.
