Looks like your apps depends upon the setuid script. you will have to set suid on it.
ll "script"
chmod 4755 will set setuid on it.

[Orhan Biyiklioglu · Accepted solution]

The following command

find / -name "unixuserinfo" -exec chmod u+s '{}' \;

will find all the files named unixuserinfo on the system an make them setuid.

However this is very dangerous because of the obvious security concerns about setuid programs. Only try it if you know what you are doing.

try to run this application as root, may be this is the application only run by root user.

check the permission of that application as ls -l . You have to set set uset ID bit as,

# chmod 4755

so that it will use setuid for specific user.

hi orhan and RAC, info provide by u is very very useful....
i find the files names unixuserinfo having the permissions as follows..

# ll /jvpc/ops/PriceMaker/Product/lib/unixuserinfo
-r-sr-sr-x 1 jvpc users 28924 Mar 1 2005 /jvpc/ops/PriceMaker/Product/lib/unixuserinfo
# ll /jvpc/ops/PriceMaker_513/Product/lib/unixuserinfo
-r-sr-sr-x 1 jvpc users 69544 Jul 13 2004 /jvpc/ops/PriceMaker_513/Product/lib/unixuserinfo
# ll /jvpc/ops/PriceMaker.error/Product/lib/unixuserinfo
-r-sr-sr-x 1 jvpc users 69544 Jul 23 2004 /jvpc/ops/PriceMaker.error/Product/lib/unixuserinfo

So the problem was the file ownership than not the permissions.

Use this

find / -name "unixuserinfo" -exec chown root '{}' \;

this will solve the problem.



PS: please assign points.

Permission of,

-r-sr-sr-x 1 jvpc users

says that,

you have setuid and setgid to jvpc user and users group. It will make problem to root user so that change ownership as like /usr/bin/passwd tool as,

-r-sr-x-r-x (4555) root:bin group.

#chmod 4555
#chown root:bin

Do this. It will work.

#chmod 4555 /jvpc/ops/PriceMaker/Product/lib/unixuserinfo and other files, also # chown root:bin /jvpc/ops/PriceMaker/Product/lib/unixuserinfo
