problem authenticating user with current CVS

[louis.botha at cs.up.ac.za]

Hi Pierre,

The same "feature" had me confused for a few hours too... :-)

setresuid() and setresgid() are only introduced in Linux kernels 2.1.44
and up.  The autoconf script isn't clever enough to figure out which
kernel you're running.  

Regards,
Louis
