401 error when accessing oamconsole

Question

I am trying to install OAM as part of one of the FEAT (SSO) in our requirements. I installed as below:
•     Installed Oracle Database
•     Ran RCU and created schema for Oracle Access Manager as in screenshot below.
•     Installed WLS
•     Installed OAIM 11g PS2
•     Created base_domain for oam_server1
•     Started Admin Server and Then Managed Server
o     First time when I started Admin Server, it took long time and the linux box hanged for more than 15 mins at the step in logs.
     [EL Info]: 2011-02-18 06:45:52.753--ServerSession(1547982985)--file:/home/oradb/Oracle/MiddlewareNew/Oracle_IDM1/oam/server/lib/oes-d8/jps-internal.jar-JpsDBDataManager login successful
o     I then terminated the server starting and restarted it followed by Managed Server
     Admin server started with the error: <OAM configuration failed. oracle.security.am.common.policy.admin.impl.PolicyValidationException: OAMSSA-06045: Validation Failure - an object of this type named "HTTP" already exists.
     Managed Server started properly without any errors in log
•     I then tried the oam-console:
o     http://abc.def.ghi.com:7001/oamconsole
     A page with just login box opened, I entered weblogic credentials : weblogic/Welcome1
     It then automatically opened another page : http://abc.def.ghi.com:14100/oam/server/obrareq.cgi?wh%3DIDMDomain+wu%3D/oamconsole/faces/pages/PolicyManager.jspx+wo%3DGET+rh%3Dhttp://abc.def.ghi.com:7001/oamconsole/faces/pages+ru%3D/oamconsole/faces/pages/PolicyManager.jspx
     Asking Enter your Single Sign-On credentials below
     I entered the same weblogic/Welcome1
o     It then throws 401 Unautorized page with the log in WLS Console.
     <Feb 18, 2011 7:17:28 AM EST> <Warning> <oracle.oam.agent-default> <BEA-000000> <OAM Server request failed: OpCode = 20 [IsAuthorizedWRefreshAndAudit], Returned Status = Major code: 9(Deny) Minor code: 2(NoCode) , extraInfo = [prefHost:IDMDomain, resource:/console/index.jsp]>
     <Feb 18, 2011 7:17:28 AM EST> <Warning> <oracle.oam.agent-default> <OAMAGENT-00408> <User is not authorized to access resource: MajorCode: DENY, MinorCode: DENY>
Would be very grateful to you if you can please help me with this issue?
Also I am not sure where and when OAM Webgates is used.
Let me know for more details required.
Thanks

In your explanation you mentioned the root cause for your issue.
First the symptoms:
- You configured OAM Domain with Database template.
- You got rid of the DB since your need development mode only.
- It took very long to start the servers in the domain.
- You can not log in correctly.
Never, ever get rid of the database. OAM stores its policies and sessions information in the database. If it takes long to start the domain, network timeouts are a possible reason. These timeouts are related to the missing database. Restart the database and everything should come up roses.
