I Need use squirrel with zimbra's ldap

[svega0]

Hello.
I migrate 5000 users from postfix+squirrel to zimbra.
All user migrate with no problem, but the performance of my server decrease when 1000 user logged in.
I need use squirrel for webmail , but I don't able authentication with zimbra's ldap.

Some suggestion ?
Thanks and sorry for my bad English.

Welcome to the forums

Perhaps a bigger server would be better ? Why do you think ZCS is causing the issue and SquirrelMail will help that ? If you could post the following it would help

su - zimbra
zmcontrol -v
top
cat /proc/cpuinfo
cat /proc/meminfo
vmstat

Sorry , I forget

Release 5.0.11_GA_2695.DEBIAN4.0 DEBIAN4.0 FOSS edition

mail:~# cat /proc/meminfo
MemTotal: 8183256 kB
MemFree: 50436 kB

proc:
model name : Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz

I put 2 options for the users,
To users "VIP" , zimbra.
To "other" (simple mortals) squirrel.

in this server run only zimbra.
I try use better perfomance, but the 4 processors top 100% and memory all 8gb and swap.

Why not create two CoS in the Admin GUI and set the VIPs to have Ajax as standard, and everyone else the standard HTML version. Also have a read of Performance Tuning Guidelines for Large Deployments - Zimbra :: Wiki especially the JVM section as you have 8GB RAM.

yeah, You Rigth!
I think you resolve my lost dreams
Thanks, I' ll try.

Sorry.
I try config COS to simple users, but this user can changue from html to ajax webmail.

Just to simplify things I'd recommend just having everyone on the Zimbra webmail. It takes one potential problem away for you since you'd only have to deal with Zimbra issues and not Zimbra + Squirrel.

Ok. I use html zimbra webmail, no squirrel.
But the problem is the user can be change from html version to java version.
I can restrict this option...?
I want the users can't change from html to advanced (Java version)
Sorry for my bad English.
And Thank for advanced
