[imp] login very slow after horde upgrade from 3.0.10 to 3.1+

[Nick Salonen]

Hi,
I haven't been able to figure out why login is so slow after upgrading horde
to 3.1+ from 3.0.10 .

There's a huge time difference when logging in between these two versions.
I use ldap authentication and imp uses hordeauth.
It doesn't matter what version of imp I use..
Any insight?

here are the pear debug logs from horde 3.1.1:

It seems to me that some preferences are taking a long time to load or imp
loads slowly, but
if i go back to using 3.0.10, login is fast again, except I don't want to
revert versions as I'd really like to use newer versions of horde

thanks,
Nick
