OK, can you file an RFE in bugzilla on [e-mail] and cc
[e-mail] and [e-mail] for this?  Not sure if this
will make 0.9 or not; I suspect probably not.  But it sounds like a
reasonable feature.

Leif: the XPCOM SDK already supports this, right?  So if somebody actually
entered the servername in the prefs dialog as two servers formatted
appropriately, would it just work?

Correct, this already works, it's handled "automatically" by the C-SDK. There
are two ways you can get failover to work with the LDAP feature in the client:

1) You setup a DNS record with multiple A-records, aka "DNS roundrobin". This
not only gives you failover, but also load balancing.

2) You can specify a list of hostnames when you configure the LDAP host entry in
the preferences file. This is a list of <space> separated host names, like

    directory1.foo.com directory2.foo.com directory3.foo.com



I've verified that both these scenarios works with the current build, so marking
this bug as INVALID. If you still have problems getting this to work, please
reopen this bug, and give me the details where it goes wrong.

Thanks,

I guess I should mention that you can configure this in the preferences dialog
as well, just type all the hostnames, separated with a <space>.

Adding robinf for documentation purposes.
