Frustrated with OracleMembershipProvider - Please help I'm losing hair!

Question

I've been trying to setup the membership provider on my local machine and have only succeeded in losing sleep and hair. Here is what I have done so far:
1. Installed Oracle 10g XE database
2. Created schema with full DBA rights
3. Installed Oracle 11g ODAC 11.1.0.5.10 Beta
4. Successfully ran ODAC sql scripts (aspnetcommon and membership)
4. Added XE schema credentials to connection string "OraAspNetConString" in machine.config
5. Added Oracle membership provider to web.config as default
6. Added Oracle.Web.dll assembly to project
Now for the problem:
I run the ASP.Net Configuration and select the 'Provider' tab.
When I choose 'Select a single provider for all site management data', only AspNetSqlProvider is shown. Where is the Oracle Provider??
When I choose 'Select a different provider for each feature (advanced)', I see the Oracle Provider for Membership and Roles. I select both then try to enter 'Security' tab. It will hang then come back with this error:
"There is a problem with your selected data store. This can be caused by an invalid server name or credentials, or by insufficient permission. It can also be caused by the role manager feature not being enabled. Click the button below to be redirected to a page where you can choose a new data store. "
What am I doing wrong?? I've searched this forum and can't find the answer.

Suggestions:
1. check your machine.config. If OracleMembershipProvider and OracleRoleProvider were not added into the entry, I recommend that reinstall Oracle Providers for ASP.NET. If all files are already copied to your system and you don't want to reinstall, you may use the OraProvCfg.exe (under your ...client_1\ASP.NET\BIN\2.x) to update your machine.config for these two providers.
2. copy sqlnet.ora and tnsnames.ora from your 10g XE installation to your 11g ODAC 11.1.0.5.10 Beta installation in the same Network\Admin location. Please search this forum for the details. You may also want to check your system environment variable TNS_ADMIN. If it's there, rename or delete it. Follow the instructions in this forum about how to check your connection.
3. if you had a successful installation, you should be able to use .NET Framework 2.0 gacutil.exe to check the assembly is listed. (Don't use 1.x gacutil.exe to check as it won't "see" it.)
gacutil /l oracle.web
4. in your application configuration file (web.config), try the second web.config example in the doc which customizes the attribute values. You may put the two sections from OracleMembershipProvider and OracleRoleProvider samples together within the <system.web> </system.web> section.
You may set the values same as your machine.config if you want to use default values. Don't forget to change the connection string on the top of the web.config.
