This comes up every now and then. Before the various federation technologies became prevalent it was a lot more common, but now not so much. Generally what you do is publish the LDAPS or GC/S port with an ACL that restricts source IPs. If the app can't failover between a couple of names then you have to put the DCs behind a load balancer.
If you really don't want to do it (which I can understand), an alternative is an AD LDS instance with bind proxies to your AD. Publish LDAPS from AD LDS and that will get you the desired effect.

It is web-based but using LDAP to authenticate users. The way it works is that a person can log a variance anonymously but then directors can use their AD credentials to log in and report their findings. My issue is that they want my two LDAP servers (which are my dc's) to have a public IP address. Even with ACL and security, I am very uncomfortable with having my DC's be "visible" on the 'net. From past experience of scanning my firewall logs, I know that a lot of times, hackers (or script kiddies) just use a range of public IP's to scan for vulnerabilities. Am I being unduly alarmist in my concern? Do other organizations attach a public IP to their LDAP servers? Thanks for any opinions you can give me. I have no problem going back to the people involved and saying ' I was wrong.' OTOH, I also have no problem telling them no way, you need to come up with a work around. ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected]<mailto:[email protected]> with the body: unsubscribe ntsysadmin ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected] with the body: unsubscribe ntsysadmin
