Hello, I've been asked to setup freeradius to talk to a SQL Server database which contains users and passwords. This was not so much of a pain but I can't figure what password encryption is used. So I had hoped somebody with some more password encryption experience could shine a light here :) In the database I've set a password to 'testing' which results in the database as: DC724AF18FBDD4E59189F5FE768A5F8311527050 This looks like a SHA algorithm? I've browsed through the source code of the program that generates these password hashes. Indeed it uses SHA. This is the library they use: http://www.aspencrypt.com/object_context.html#CreateHash. They use the 'calgSHA'. But when I set the Password attribute in freeradius to SHA_password it doesn't match. It reads the database succesfully when I set User_password and use the hash as a password: radtest test@bla.com DC724AF18FBDD4E59189F5FE768A5F8311527050 localhost 0 testing123 Sending Access-Request of id 61 to 127.0.0.1 port 1812 User-Name = "test@bla.com" User-Password = "DC724AF18FBDD4E59189F5FE768A5F8311527050" NAS-IP-Address = 255.255.255.255 NAS-Port = 0 rad_recv: Access-Accept packet from host 127.0.0.1:1812, id=61, length=43 Service-Type = Framed-User Tunnel-Type:0 = VLAN Tunnel-Medium-Type:0 = IEEE-802 Tunnel-Private-Group-Id:0 = "132" But when I change User-Password to SHA-Password it doesn't match: radtest test@bla.com testing localhost 0 testing123 Sending Access-Request of id 131 to 127.0.0.1 port 1812 User-Name = "test@bla.com" User-Password = "testing" NAS-IP-Address = 255.255.255.255 NAS-Port = 0 Re-sending Access-Request of id 131 to 127.0.0.1 port 1812 User-Name = "test@bla.com" User-Password = "testing" NAS-IP-Address = 255.255.255.255 NAS-Port = 0 rad_recv: Access-Reject packet from host 127.0.0.1:1812, id=131, length=20 So this isn't a SHA password hash? I don't know for sure if this the same encryption method but 'echo testing | openssl sha' generates a different hash: 581165b0cc90703a8e669d91effba108fbe2c83c Rg, Arnaud -- View this message in context: http://www.nabble.com/PAP-what-password-encryption-is-used--tp18887393p18887...
