I tried it and it worked.
However, it worked only because the specific statement was :
"Framed-IP-Address = IP.ADD.RE.SS"

(Remind : the wanted behaviour is
I want the following behaviour :

1) Set the password for the user
2) Authentication of the user
3) X is always added to the reply if the user is authenticated
4) Moreover, Y is added to the reply for NAS, still if the user is 
authenticated.)

What I would like instead of my dumb radipusers table (id | username | 
ip), is a table which looks like radreply (id | username | attribute | 
op | value) I could use with unlang.

The thing I want to be added by radius in the reply :
if (Huntgroup-Name == 'one_huntgroup_name') {
    Attribute1 op1 value1
    Attribute2 op2 value2
    ...
    Attributei opi valuei
}
Given that Attribute,op,value 1...i are in the MySQL table.

Is it possible to get that by unlang / SQL ? I've read the unlang 
manpage, and I don't see any information which would enable me to do 
that.
I've tried something without so much hope, and without success :
"%{sql:SELECT attribute from radreply where 
username='%{request:User-Name}'}" = "%{sql:SELECT value from radreply 
where username='%{User-Name}'}"

Thank you for your help,
