ok, that brought us a step further.
If we like to create custom groups like in the rlm_passwd, do we have to write our own rlm c module? If so, may you point me to the documentation of how to write those modules? Uh... no. Did you even bother reading the documentation I suggested? It tells you how to create custom groups *without* writing C coe. I've read through the /etc/freeradius/modules/passwd file a few times again and I'm still not 100% sure, do I just have to write a new module file like /etc/freeradius/modules/myCustomersModule and fill it with for example: group_customer1 { format = "*.customer1" } group_customer2 { format = "*.customer2" } As far as I can see, this should then be accessible through an unlang script, right?
