I have configured Zimbra-4.04 on CentOS-4.4. I am using external LDAP (SAMBA PDC) for authentication. For getting email address as same as my current addresses, i set aliases for each account ( ie, firstname.lastname@example.org has an alias as email@example.com). Things are going well, but regarding my GAL, i am using internal authentication. Now the problem is that when i searching from Global Address List, it showing both "email address and aliases", but i want only aliases. Is there any option to filter internal GAL for alias only..
