[exim] server_set_id no longer working?

The below auth when it fails

spa_auth:
                driver                          = spa
                public_name               = NTLM
                hide server_password  = ${lookup
mysql{NTLM_AUTH}{$value}fail}
                server_set_id              = $1

used to give me

2012-11-05 17:20:18 spa_auth authenticator failed for <hostname> [IP
number]: 535 Incorrect authentication
data (set_id=<authid>)

After the upgrade to 4.80.1 I only get

2012-11-05 18:10:59 spa_authenticator authenticator failed for <hostname>
[IP number]: 535 Incorrect authentication
data


I have tried 2,3 as well and it still does not output what I require which
is the authid. If I downgrade to exim 4.77 It works as Before.

exim -d+all output

18:10:59 30068    result: <pass>
18:10:59 30068 expanding: $1
18:10:59 30068    result:
18:10:59 30068 SMTP>> 535 Incorrect authentication data
18:10:59 30068 LOG: MAIN REJECT

Thanks for any help
