You mean when the "user" tries to do "chown" it fails?
Who owns that file?

If you want that "user" to "chown" the file which doesn't belong to him, you can make use of sudoers.

Add an entry like this to /etc/sudoers. use visudo to edit the /etc/sudoers file
Code:
user     ALL=NOPASSWD:/usr/bin/chown

And then ask the user to do something like this to own the file
Code:
sudo chown user:group file

*** Be advised, the command chown will now run as root for that particular user! ***

BTW, which is your OS? sudo is for Linux. If solaris, you can look into RBAC.

chown(1B)					     SunOS/BSD Compatibility Package Commands						 chown(1B)

NAME
chown - change owner SYNOPSIS
/usr/ucb/chown [-fR] owner[.group] filename... DESCRIPTION
chown changes the owner of the filenames to owner. The owner can be either a decimal user ID (UID) or a login name found in the password file. An optional group can also be specified. The group can be either a decimal group ID (GID) or a group name found in the GID file. In the default case, only the super-user of the machine where the file is physically located can change the owner. The system configura- tion option {_POSIX_CHOWN_RESTRICTED} and the privileges PRIV_FILE_CHOWN and PRIV_FILE_CHOWN_SELF also affect who can change the ownership of a file. See chown(2) and privileges(5). OPTIONS
The following options are supported: -f Do not report errors. -R Recursively descend into directories setting the ownership of all files in each directory encountered. When symbolic links are encountered, their ownership is changed, but they are not traversed. USAGE
See largefile(5) for the description of the behavior of chown when encountering files greater than or equal to 2 Gbyte ( 2^31 bytes). FILES
/etc/passwd Password file ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWscpu | +-----------------------------+-----------------------------+ SEE ALSO
