SDE on SQL Server

[Bill TenBroeck]

Has anyone had any luck connecting using the "Single database Model" on SQL
Server. (Each DB stands alone and has its own service and port number.)

I have 2 servers set up, one using the "multiple database model" and can
connect to Mapserver successfully. Against the single database model server
I'm getting the following error:

msSDELayerOpen(): SDE error. SE_connection_create(): Invalid database name.
(-162)

I am using the following in the layer definition:

    CONNECTIONTYPE SDE
    CONNECTION "BILLP4,port:5155,sde,xxx,xxx"
    DATA "BOUND_SDE.SDE.STATESP020,SHAPE"

On the DATA line I have tried every permutation I can think of; the example
shown is the way it shows up in ArcExplorer.
