--- Doc Text *updated* ---
Cause: When enabling support for POSIX ACLs on a FUSE mount with the "-o acl" mount option, permission checks only use the first 32 groups of a user. 

Consequence: If permissions of a directory/file are permitted by groups further in the group-list, the permissions are not applied. The group-list of the user is truncated to the fist 32 groups.

Fix: A new mount option "resolve-gids" is introduced to overcome 32-groups limit

Result: By enabling the "resolve-gids" option, the fuse-bridge will call getgrouplist() to retrieve all the groups from the user accessing the mountpoint, which could be >32.
