After adding the setuid flag to your app you should be able to run the application with a standard user account.
Quote:
setuid and setgid (short for set user ID upon execution and set group ID upon execution, respectively) are Unix access rights flags that allow users to run an executable with the permissions of the executable's owner or group. They are often used to allow users on a computer system to run programs with temporarily elevated privileges in order to perform a specific task. [...] - http://en.wikipedia.org/wiki/Setuid

fs_setcell
FS_SETCELL(1) AFS Command Reference FS_SETCELL(1)NAME
fs_setcell - Configures permissions for setuid programs from specified cells
SYNOPSIS
fs setcell -cell <cell name>+ [-suid] [-nosuid] [-help]
fs setce -c <cell name>+ [-s] [-n] [-h]
DESCRIPTION
The fs setcell command sets whether the Cache Manager allows programs (and other executable files) from each cell named by the -cell
argument to run with setuid permission. By default, the Cache Manager allows programs from its home cell to run with setuid permission, but
not programs from any foreign cells. A program belongs to the same cell as the file server machine that houses the volume in which the
program's binary file resides, as specified in the file server machine's /etc/openafs/server/ThisCell file. The Cache Manager determines
its own home cell by reading the /etc/openafs/ThisCell file at initialization.
To enable programs from each specified cell to run with setuid permission, include the -suid flag. To prohibit programs from running with
setuid permission, include the -nosuid flag, or omit both flags.
The fs setcell command directly alters a cell's setuid status as recorded in kernel memory, so rebooting the machine is unnecessary.
However, non-default settings do not persist across reboots of the machine unless the appropriate fs setcell command appears in the
machine's AFS initialization file.
To display a cell's setuid status, issue the fs getcellstatus command.
CAUTIONS
AFS does not recognize effective UID: if a setuid program accesses AFS files and directories, it does so using the current AFS identity of
the AFS user who initialized the program, not of the program's owner. Only the local file system recognizes effective UID.
Only members of the system:administrators group can turn on the setuid mode bit on an AFS file or directory.
When the setuid mode bit is turned on, the UNIX "ls -l" command displays the third user mode bit as an "s" instead of an "x". However, the
"s" does not appear on an AFS file or directory unless setuid permission is enabled for the cell in which the file resides.
OPTIONS -cell <cell name>+
Names each cell for which to set setuid status. Provide the fully qualified domain name, or a shortened form that disambiguates it from
the other cells listed in the local /etc/openafs/CellServDB file.
-suid
Allows programs from each specified cell to run with setuid privilege. Provide it or the -nosuid flag, or omit both flags to disallow
programs from running with setuid privilege.
-nosuid
Prevents programs from each specified cell from running with setuid privilege. Provide it or the -suid flag, or omit both flags to
disallow programs form running with setuid privilege.
-help
Prints the online help for this command. All other valid options are ignored.
EXAMPLES
The following command enables executable files from the State University cell to run with setuid privilege on the local machine:
% fs setcell -cell stateu.edu -suid
PRIVILEGE REQUIRED
The issuer must be logged in as the local superuser root.
