I have multiple users on the system. Each user has its own group. I would like to have a single user that can access files in the users home dir's if they set the relevant group read/write bits. So I add the global user to each of the users groups. This works fine until the global user is a member of 15 groups. Adding the user to successive groups works, but the global user is unable to access any files that are g+r on any groups that were added after the 14th. >How-To-Repeat: example : cat /etc/groups globaluser:*:1000: user1:*:1001:globaluser user2:*:1002:globaluser user3:*:1003:globaluser user4:*:1004:globaluser user5:*:1005:globaluser user6:*:1006:globaluser user7:*:1007:globaluser user8:*:1008:globaluser user9:*:1009:globaluser user10:*:1010:globaluser user11:*:1011:globaluser user12:*:1012:globaluser user13:*:1013:globaluser user14:*:1014:globaluser user15:*:1015:globaluser user16:*:1016:globaluser cd /home ls -al drwxr-x--- 3 user1 user1 512 Jul 26 21:26 user1 drwxr-x--- 3 user2 user2 512 Jul 26 21:26 user2 drwxr-x--- 3 user3 user3 512 Jul 26 21:26 user3 drwxr-x--- 3 user4 user4 512 Jul 26 21:26 user4 drwxr-x--- 3 user5 user5 512 Jul 26 21:26 user5 drwxr-x--- 3 user6 user6 512 Jul 26 21:26 user6 drwxr-x--- 3 user7 user7 512 Jul 26 21:26 user7 drwxr-x--- 3 user8 user8 512 Jul 26 21:26 user8 drwxr-x--- 3 user9 user9 512 Jul 26 21:26 user9 drwxr-x--- 3 user10 user10 512 Jul 26 21:26 user10 drwxr-x--- 3 user11 user11 512 Jul 26 21:26 user11 drwxr-x--- 3 user12 user12 512 Jul 26 21:26 user12 drwxr-x--- 3 user13 user13 512 Jul 26 21:26 user13 drwxr-x--- 3 user14 user14 512 Jul 26 21:26 user14 drwxr-x--- 3 user15 user15 512 Jul 26 21:26 user15 drwxr-x--- 3 user16 user16 512 Jul 26 21:26 user16 su globaluser ls -al user1 drwxr-x--- 3 user1 user1 512 Jul 26 21:26 . drwxr-xr-x 22 root wheel 512 Jul 27 19:54 .. ls -al user10 drwxr-x--- 3 user10 user10 512 Jul 26 21:26 . drwxr-xr-x 22 root wheel 512 Jul 27 19:54 .. ls -al user15 ls: user15: Permission denied >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
