A relatively "popular" solution I have seen for things like this is to have
some small perl script that is launched instead of the app itself and that
perl script does a site based lookup on the spot for the SRV record, tests
to make sure the GC is responding, and then slams that into the
configuration and then starts the app. That way if there is an issue, you
simply restart the app and all is well.
 
You can also set up a CNAME that points to GCs, but if you have a GCs out in
sites, you will probably be setting up quite a few aliases. Then every site
selects the proper alias for their site. That is seriously a pain to keep
all synced up properly and is a likely place for maintenance to fall behind
and cause issues unless someone automates those updates. 
 
The problem is simply that the app isn't SRV record aware, that isn't a
Microsoft thing, that is an RFC thing. Not so evolved eh? But it is open
source, someone could always quickly and easily add proper SRV lookup
capability. <eg>

Hi,

 

I have a mix of Windows and Linux users. Most of my Linux users use
Evolution as a mail client which needs to point to a GC for its
configuration. 

 

My question is does anyone know a way to basically round robin a wildcard
entry for those mail clients? So in case the DC/GC they're pointing to
crashes half my users won't have to re-point their clients.

 

Thanks in advance -

Mike
