Since I am installing the WSS on the same server which will be used as FIM Portal server...so I am wondering which service account will be used as mentioned in the above step - The SA for FIM Portal or WSS 3.0

3. Can I configure this thing w/o SSL atleast to see if it works.

4. During registring the SPN, it says that it is recommended to use alias. Agreed. Later, the installation guide also says this -The <alias> above is the address that is entered during FIM Service setup and used by the clients and the FIM Portal to contact the Web Service. This can be an alias (CNAME) or host (A) resource record in DNS. If you are using Network Load Balancing (NLB), this is the name of the cluster."

I checked the screenshots in the installation guide...I dont see any step in the wizard..which ask for this alias.

Can anybody help with these. Also please share any best practices ot any detailed step by step guide which can help me with this installation.
