You should not use user listings with 14000 users, because this simply 
doesn't scale in Horde. And if you have 14000 users, you probably have 
a separate user management interface anyway. Don't misunderstand, 
Horde itself scales well, just not the user listings, for example in 
the share interfaces.

If you want to extend Horde to support such large listings or improve 
Horde's user managment, file an enhancement request.

If you have any intention of using Horde for anything, with 14,000 
users, you're definitely going to have to give PHP more than 8MB of 
memory...



Although I agree that some sort of pagination is usually helpful for 
large arrays of elements, rather than presenting the user with a 
loooong list..

Hi,



I am using horde-3.1.1 with qmail-ldap and fedora ldap server. I have 
about 14,000 users inthe ldap directory. When I click Administration 
-> Users,  nothing comes. Looking at apache error logs, I get a message:

Allowed memory size of 8388608 bytes exhausted (tried to allocate 12 bytes)



The ldap query is



SRCH base="o=isp" scope=2 filter="(&(objectClass=qmailuser))" attrs="uid"



which would return all 14,000 users. It seems php gets out of memory 
error when it is trying to process all the users at once. An obvious 
solution would be to limit the number of records fetched at once.
