[srslte-users] MAC Authentication failure

[Pedro Alvarez]

Perhaps you forgot to set the UE's authentication algorithm? I don't
see you setting that in the command line arguments of the UE and
commercial EPCs usually use milenage (by default srsUE uses XOR).
Also, if you can't see the PCAP, try setting the DLT user (see the ue
configuration file for some instructions)

Can you help me figure out where might be the problem(Why is authentication failing, if all the parameters are set properly)? I would appreciate any help that could lead me further!
