[horde] Logging into Horde is slow

[Laura McCord]

When users log into Horde I have been getting complaints that it is too
slow. It takes about 15-30 seconds for their inbox to appear. We were
using an older version of Horde before and we created another mail
server with the newest version of Horde, but this one seems to take
awhile opening up. However, this is the first time we are using ldap as
the authentication source. We have Kronolith, Vacation, Forwards,
Password, Nag, Imp and Turba modules installed. Does anyone have any
suggestions on where I should look first?

Thanks,
 Laura
