"Interesting" ? Yes, perhaps...as far as I am concerned, that's not the 
word i'd have used :-)
Of course, I have php4 on my Kubuntu :-\
Do you mean I must upgrade to php5 ?
And if so, how can I do that since I work with a Kolab server that runs 
natively php 4 ? (and first, is it possible ??)
It remains that it worked before and that I don't know why I can't use 
this functionnality anymore.
But, perhaps can I adjust theese rights directly thrue cyradm ?

I'm afraid not to clearly understand what this means...
I'm quiet new to Unix world and I've got lots of deficiencies (my real 
experiment begins with Kolab/Horde in fact :-[ )
Can you explain me a little bit accurately ?
