>Description:
Single user, member of multiple groups.
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
