[turba] turba is slow with ldap

[Eric.Doutreleau at int-evry.fr]

Well i have just installed the cvs version of horde and turba and i 
succesfully set up an LDAP source.

But i have the following problem.

the ldap query is awfully slow when

-I use it from imp
-I make a "normal search"

But when i made an Advanced search it works quite well. ( not very fast
but acceptable like several seconds ).

The same request in the two first case give me the result after more than
one minute.

Has someone already seen this problem?

Thank in advance for any help
