If your users prefer to use client apps like Thunderbird, or Mac's Address book but still needs to access the Zimbra's GAL, here's a proposed workaround.
Configure ZCS machine(Optional)
Disable LDAP anonymous connections
/opt/zimbra/libexec/zmldapanon -d
Configure Client
Example for a Zimbra server called mail.abccompany.com with a domain of abccompany.com
The settings would have something like this:
Server: mail.abccompany.com
Search Base: ou=people,dc=abccompany,dc=com
Port: 389
Scope: subtree
Authentication for a user with the address of joe@abccompany.com
uid=joe,ou=people,dc=abccompany,dc=com
password: _zimbra_password_
Authentication Type: simple
Regarding External Authentication
See, https://bugzilla.zimbra.com/show_bug.cgi?id=50248
Outside Company's Network
If a user has the need to access the GAL from outside the company network, most likely port 389 will need to be accessible.
startTLS Requirement
Zimbra 6.0 has the ability to require startTLS (SSL encryption) over ldap connections (not ldaps://).
The security value assigned to startTLS connections depends on the strength of the certificate that the server is using.
You can find the strength of the current cert by examining /var/log/zimbra.log when the ldap log level includes stats logging(256):
Aug 4 21:42:47 gort slapd[32703]: conn=726 fd=12 TLS established tls_ssf=128 ssf=128
This indicates the tls_ssf (startTLS security factor) is 128, so you would use that as the value for the key.
zmlocalconfig -e ldap_common_require_tls=128
zmcontrol stop
zmcontrol start
Note:
Java can go as high as 128. But other java apps can to higher. If you set ldap_common_require_tls to 256, all java apps will fail. So you could see tls_ssf=256, in your log.
Just to be safe, just use 128 for ldap_common_require_tls.
