Setting Service-Type

[Rowley, Mathew]

I have a perl module that I want to set the Service-Type attribute, but am getting this error:

Tue Oct 26 14:54:25 2010 : Debug: rlm_perl: ERROR: Failed to create pair Service-Type = Administrative-User

I am thinking its due to the request having the Service-Type already set. Does anyone know if its possible to override that?

I have also tried to just statically set the Service-Type in the users file via:
DEFAULT
Service-Type = Administrative-User

Nothing seems to set it. The request looks like:
rad_recv: Access-Request packet from host 10.252.152.93 port 32769, id=43, length=79
User-Name = "user"
User-Password = "pass"
Service-Type = NAS-Prompt-User
NAS-IP-Address = 10.252.152.93
NAS-Identifier = "Security_lab"

Anyone have ideas on how I can change the Service-Type?
