GAL sync to all sub-domains?

[tiger2000]

Dear All,

i just read the wiki article : GAL Sync Account - Zimbra :: Wiki and i'm still not sure if this could solve my requirement.

we create several sub domains in one Zimbra server (6.0.4 NE), such as:

sub1.domain
sub2.domain
sub3.domain

i also notice that i have three accounts :
galsync@sub1.domain
galsync@sub2.domain
galsync@sub3.domain

and is it possible to allow user1@sub1.domain to look for the GAL of @sub2.domain and @sub3.domain ??

i've made change to polling interval but nothing changed.

any advice? Thanks.
