TACACS+ configuration: how to receive priv-lvl value?

Question

I need to configure TACACS+ server to know if the given user is authenticated* and what is his priv-lvl. As a client I'm using tactest (tacacs.net) and TACACS+ Client Java Library (AXL).

I tried with this:

user = admin {
    name = “Admin User”
    login = cleartext admin
    service = exec {
      priv-lvl = 10
  }
}

and can authenticate as an admin but can't get his priv-lvl.

Here is the output from tactest:

C:\Program Files (x86)\TACACS.net>tactest -s x.x.x.x -k testing123 -u admin -p admin -author -service exec
Trying to open connection to x.x.x.x:49

Sending:

Priv lvl=1

SessionID=494431516
DataLength=6

Is there a way to get that attribute value?

*I'm aware that it isn't only authentication but also kind of authorization

I finally found a solution. I just had to change service name to any other:

user = admin {
    name = “Admin User”
    login = cleartext admin
    service = myservice {
      priv-lvl = 10
  }
}

Then I was able to get AV pair on client side:

Received Header:
MajorVersion=12
MinorVersion=0
Type=Authorization
SeqNum=2
IsEncrypted=True
IsSingleConnect=False
SessionID=952769599
DataLength=18

Received Body:
 Authorization Status=PassAdd
User=
Port=
Args: priv-lvl=10
