[coLinux-devel] Changing the ownership(UID) of a program when lounging

[sena s. <aun...@ce...>]

Dear Sir/Madam,

I have a server written in C which is supposed to be lounging executables 
to selected UIDs

Say the server is running under "herft" uid=501

I want to lounge  exec-1 under "user5a"-- uis=503
and
exec-2  under "user5b"-- uid=504.


currently both exec-1 and exec-2 are owned by "herft"

I have done it this in the following way:
  If the server runs under root this is possible. what I have done was 
having another intermediate processor called  "lounger.exe" which would be 
started by my server under "root" then changes to user5a or user5b starts 
the exec and dies.
It is easy to transfer the ownership from root to any other

My Question is this....

But if the server runs under another account which has the same 
privileges  say "herft" How can we do this? Therefore the lounger.exe too 
will run under this.
But transferring the ownership from herft to user5a or user5b ?

Thanks
