Dear All,
I have little problem, our client ( Thunder Bird, Outlook, OE ) can't access GAL.

There is my server configuration :

B. Client Setting
Based configuration at= Mail Client LDAP Configuration - Zimbra :: Wiki

Thunder Bird Client Configuration
Under General tab
* Name = Zimbra LDAP
* Hostname = xxx.102.96.xxx
* Base DN = ou=people,dc=xxx,dc=asia
* Port = 389
* Bind DN = (leave blank)
* SSL = (leave unticked)

Under Advanced tab
* Don't return more than = 500
* Scope = Subtree
* Search filter = (mail=*)

When I select Directory Service Property -> Offline, then click "Download now", status replication success.
But when I try by creating a new email and in the To: start typing a name, result: not appear any email address.

With same configuration I try at Outlook 2007 & Outlook Express, GAL Zimbra still can't access by client.

Then I try install Zindus a adds-on Thunder Bird, My thunder bird success syn with Zimbra & I can access GAL.

Have any advice & solution ?.
