I know that changing users and groups is pretty basic admin, but this one has got me stumped. When I try to change the group of a file for which I am the owner for, it still gives me a 'Not owner' error.
For example, when I am logged in as 'webadmin', I have the following file:

lfc-setacl
LFC-SETACL(1) LFC User Commands LFC-SETACL(1)
NAME
lfc-setacl - set LFC directory/file access control lists
SYNOPSIS
lfc-setacl [-d] [-m] [-s] acl_entries path...
DESCRIPTION
lfc-setacl sets the Access Control List associated with a LFC directory/file.
acl_entries is a comma separated list of entries. Each entry has colon separated fields: ACL type, id (uid or gid), permission. Only direc-
tories can have default ACL entries.
The entries look like:
user::perm
user:uid:perm
group::perm
group:gid:perm
mask:perm
other:perm
default:user::perm
default:user:uid:perm
default:group::perm
default:group:gid:perm
default:mask:perm
default:other:perm
The ACL type can be abbreviated to the first letter. The first "user" entry gives the permissions granted to the owner of the file. The
following "user" entries show the permissions granted to specific users, they are sorted in ascending order of uid. The first "group"
entry gives the permissions granted to the group owner of the file. The following "group" entries show the permissions granted to specific
groups, they are sorted in ascending order of gid. The "mask" entry is the maximum permission granted to specific users or groups. It
does not affect the "owner" and "other" permissions. The "mask" entry must be present if there are specific "user" or "group" entries.
"default" entries associated with a directory are inherited as access ACL by the files or sub-directories created in that directory. The
umask is not used. Sub-directories also inherit the default ACL as default ACL. As soon as there is one default ACL entry, the 3 default
ACL base entries (default user, default group, default other) must be present.
The entry processing conforms to the Posix 1003.1e draft standard 17.
The effective user ID of the process must match the owner of the file or the caller must have ADMIN privilege in the Cupv database.
path specifies the LFC pathname. If path does not start with /, it is prefixed by the content of the LFC_HOME environment variable.
uid can be given as the username or the corresponding numeric id.
gid can be given as the groupname or the corresponding numeric id.
perm can be expressed as a combination of characters rwx- or as a value between 0 and 7.
OPTIONS
-d remove ACL entries. The "perm" field is ignored.
-m modify existing ACL entries or add new entries.
-s set the ACL entries. The complete set of ACL entries is replaced.
EXAMPLES
Let's create a directory:
lfc-mkdir /grid/atlas/test/file.log/d6
and add write permission for user bcouturi:
lfc-setacl -m u:bcouturi:rwx,m:rwx /grid/atlas/test/file.log/d6
Let's create a directory:
lfc-mkdir /grid/atlas/test/file.log/d7
and add default ACLs to it:
lfc-setacl -m d:u::7,d:g::7,d:o:5 /grid/atlas/test/file.log/d7
Let's check the resulting ACLs:
lfc-getacl /grid/atlas/test/file.log/d7
# file: /grid/atlas/test/file.log/d7
# owner: baud
# group: c3
user::rwx
group::r-x #effective:r-x
other::r-x
default:user::rwx
default:group::rwx
default:other::r-x
Let's create a sub-directory and check the resulting ACLs:
lfc-mkdir /grid/atlas/test/file.log/d7/d2
lfc-getacl /grid/atlas/test/file.log/d7/d2
# file: /grid/atlas/test/file.log/d7/d2
# owner: baud
# group: c3
user::rwx
group::rwx #effective:rwx
other::r-x
default:user::rwx
default:group::rwx
default:other::r-x
Let's create a file in the same directory and check the resulting ACLs:
lfc-touch /grid/atlas/test/file.log/d7/f2
lfc-getacl /grid/atlas/test/file.log/d7/f2
# file: /grid/atlas/test/file.log/d7/f2
# owner: baud
# group: c3
user::rw-
group::rw- #effective:rw-
other::r--
EXIT STATUS
This program returns 0 if the operation was successful or >0 if the operation failed.
