I don't know this tool. The fact that it prints the unknown accounts with '+' and the known account with '\' is weird. This shouldn't happen. It should print all accounts with a '+'. Please use `getfacl' to examine the ACLs. > > I tried tar in an existing dir: > > > mkdir test > > tar caf test.tar test > > ll test > total 0 > > cd test > > tar xaf ../test.tar > > ll > total 0 > drwxrwxr-x+ 1 0 Aug 22 15:26 test/ > > lsacl test > [u::rwx,g::rwx,g:Bliss\lawgroup:rwx,g:Bliss\Domain Admins:rwx,m:rwx,o:r-x/ > u::rwx,g::rwx,g:Bliss\lawgroup:rwx,g:Bliss\Domain Admins:rwx,m:rwx,o:r-x] > test > > With the above and only standard separator chars, no problem > > I'm guessing, but '+' is a reserved char that's not permitted in > acl_to_text... No, that's a wrong assumption. Think about it. The ACL given to acl_to_text is the binary form, so it doesn't contain user or group names, only uids and gids. The usernames are only generated in the output. EINVAL from acl_to_text means the incoming acl is invalid. Either it's so broken that acl_to_text crashes, or it'sa NULL pointer, or it has less then MIN_ACL_ENTRIES (3) entry, or it has more than MAX_ACL_ENTRIES (2730) entries, or it doesn't follow the required rules for POSIX ACLs. I assume the latter is the case here. *Why* this occurs, I can't tell. I'd need a simple, reproducible testcase for that.
