$ whoami
zafer

$ id
uid=1001(zafer) gid=100(users) groups=100(users),0(wheel),1003(project3),1004(project4),1005(project5),1006(project6),1007(project7),1008(project8),1009(project9),1010(project10),1011(project11),1012(project12),1013(project13),1014(project14),1015(project15),1016(project16)

This seems ok. 

$ id zafer
uid=1001(zafer) gid=100(users) groups=100(users),0(wheel),1003(project3),1004(project4),1005(project5),1006(project6),1007(project7),1008(project8),1009(project9),1010(project10),1011(project11),1012(project12),1013(project13),1014(project14),1015(project15),1016(project16),1017(project17),0(wheel)

Here group 0 is shown twice and group Project17 is shown.

zafer is Member is 18 groups, should id show all 18 or is there a limitation to 16 ?
