How to setting oscam.user for reshare???

Hello, i'd like reshare a c line with oscam!!!
If for example a friend of mine gave me a c line with reshare, how do I set it in oscam.user?
i've server ubuntu with only oscam.

In cccam.cfg i set F: server port user psw {0:0:2}
In oscam how do I set it?

Thanks
