Hi,

Finally, my peer found the way to set the correct syntax:

Cmnd_Alias CHMOD   = /usr/bin/chmod u+x /dir/where/chmod/is/allowed/*

I was missing the chmod options u+x. Sure, this line only sets 
executable-by-owner bit but, it's enough for me so far.

Thank you Patrick for sharing your Perl wrappers for chmod and chown. I am 
still studying them :-)
