Supplementary groups ? and group? what is the difference?
Hi all
I don't know what is Supplementary groups and Group. When I check Linuxconf, I see that user of my ftp belong to different Group and same Supplementary groups, what does it mean?

Group is the main group and can be only one. 'Suplementary groups' is a place for all other groups (there's a limit on number of groups for one user, but it's hard to get to it) . There's not big difference.

so like you said, if their main group is group1, group2,.. but their Suplementary Group is newgroup, and if I point them to folder1, all users have same Suplementray group will be point to same place?

What o you mean when you write 'point to some place'? Home directory? Beeing in a group means you can access files/directories with group equal to one of your groups (of course, the permissions may be different, for example when owner has read/write/execute, group can have read/execute and other users may have no access to the file).
