I just migrated the DHCP service from our 10.4 servers to some new 10.5.6 servers. It seems that in Leopard server, there can be only one search doamin defined as the default domain in the DHCP scopes. You can put more than one in the field, but only one shows up on the 10.5 clients. The interesting part is that on the printers with static maps they get all three search domains. While the clients still only get one.
This is not the same behavior as Tiger server, where you could specify multiple search domains separated by a comma and they would show up on the client.
The only fix now is to hard code the search domains into every machine on our network that is using DHCP (around 230). This is a problem if we ever need to change or add domains to the search base.
From ARD's 'Send Unix command...' or in Terminal.app do:
networksetup -setsearchdomains <networkservice> <domain1> \[domain2] \[...]
Where <networkservice> is the network interface that you wish to set the search domains for, <domain1> is the primary search domain, \[domain2] is a secondary search domain, and \[ . . . ] are any additional search domains.
For more usage of the 'networksetup' command type it into Terminal.app.
