Workflow + Single Sign-on: 503 Service Temporarily Unavailable Error

Question

Hello.
I've the following system:
Windows 2000 Professional Edition
DB Oracle 9i: OraDb9i_home1
AS 10g as Infrastructure (in order to use it as a provider for Single Sign-on): OraAs10g_home1
AS 10g as Development (in order to use it as Application Server to run Workflow 2.6.3 processes): OraAs10g_home2
The name of my host is cami5 (local IP address 192.168.0.14)
I can succesfully log in the OraAs10g_home1 enterprise manager via http://cami5:1810 as ias_admin, and it reports me that OID
and Single Sign-on:orasso are up and running (and LDAP is up: via a netstat -an command I see that the related ports, TCP 389
and 636, are in listening, and investigating I see that they are binded from oidldapd.exe).
I can succesfully log in the OraAs10g_home2 enterprise manager via http://cami5:1811 as ias_admin, and it reports me that
HTTP_Server is up and running (it is binded to the 80 port).
If I configure a DAD via PLP/SQL Properties in the Administration tab, I can choose from different authentication modes.
If I select "Basic", it runs fine.
i.e., I've made a very basic workflow process, I deployed it to /pls/wf1, and browsing http://cami5/pls/wf1/wfa_html.home
it runs fine.
But, if I select "Single Sign On" authentication mode (the one I have to choose because of some specs I have to satisfy), the
service is deployed without any errors to /pls/wf2, but then it is reported as down in the DADs list, and if trying to go to
http://cami5/pls/wf2/owf_mgr.home it appears as:
Service Temporarily Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again
later.
Oracle-HTTP-Server/1.3.28 Server at CAMI5 Port 80
The same identical thing happens if I try to configure the DAD via the "Mod_plsql Configuration Menu" in http://localhost:7778
Where am I wrong?
The error description reported by the http server is telling the real problem, or have I missed something else?
What can I do in order to solve the problem?
Any suggestion is appreciated.
Thank you in advance.
Regards,
Umberto

Raja,
thank you for your help.
Unfortunately it didn't solve the problem.
Yes, I installed wf263 from CMSDK_9.0.4.1.0_RTM.
But during the installation, the workflow configuration assistant didn't show me any SSO option to be choosed: it just asked me about LDAP parameters, and I provided it following data:
Host Name: cami5 (it is the host name of the machine that is running the LDAP server via the Oracle IAS 10g Infrastructure)
Port No.: 389
User Name: cn=orcladmin
Old Password: cami5 (the password I used)
Log Base and User Base: (nothing, I left it blank)
I already followed the metalink notes you've suggested me (Oracle Workflow 2.6.3 Installation Update), but the "Workflow Manager" link still not appeared in the AS Enterprise Manager: I can just see the "WFALSNRSVCApp" and the "WFMLRSVCApp" Applications. In order to get to the workflow manager I had to deploy the dad via the Mod_plsql Configuration menu in the http...:7778 service provided by the AS instance in which was installed the workflow component. (I never was able to let that link to appear, even in new installations on other computers reinstalled from scratch).
Any other suggestion?

Umberto
