If I use the Key returned from yp_first or yp_next, on my systems (Solaris 2.6/2.7/2.8 either sparc/Intel), the yp_next return every time the same entry.

I've discovered, after some hours of debugging, that php add a CR at the end of the key, so the keylength is bigger than the real keylength of 1 char.
Stripping it, php is definitely happy.

I wrote some lines to show that... use them as you think better

Thanks.
