OAM 11g - UCM Integration

I have been involved with many customer's who are integrating OAM 11g with Universal Content Manager 11g (UCM) and I know that trying to follow the OAM documentation can be daunting. So I put together my own integration document/Blog. Not to re-invent the wheel, this post utilizes what we already have in terms of documentation. Think of this as a checklist and the steps that I implemented to get my own internal environment working.

Prerequisites

1. Install and configure UCM
2. Install a weblogic plug-in on OHS that fixes a bug for UCM. http://www.oracle.com/technetwork/middleware/ias/downloads/wls-plugins-096117.html

High Level Steps/Checklist

1. Configure an OHS server to proxy all request to UCM (/cs, /adfAuthentication and /_ocsh).
2. Register a webgate with the URL’s you want to protect.
3. Configure an OAM Identity Asserter and LDAP/OVD provider in Weblogic.
4. Validate users can access UCM with WLS Security.
5. Install a webgate on OHS server and validate.

Detail Steps

1. Follow the documentation to configure OAM Access Manager 11g with Oracle UCM, Section 5.2.3.1: http://download.oracle.com/docs/cd/E21764_01/doc.1111/e10792/c03_security.htm#CDDHGCCC

Note: The documentation is not clear whether to install the Webgate on the OHS server first. Recommend to install the webgate at the end.

5.2.3.1 - Configuring Oracle Access Manager 11g with Oracle UCM
1.a. In our use case, we only need to protect the UCM URI’s below.

# UCM Content Server

<Location /cs>

SetHandler weblogic-handler

WebLogicHost <hostname>

WebLogicPort <portnumber>

</Location>

# UCM Content Server authentication

<Location /adfAuthentication>

SetHandler weblogic-handler

WebLogicHost<hostname>

WebLogicPort <portnumber>

</Location>

#UCM online help

<Location /_ocsh>

SetHandler weblogic-handler

WebLogicHost <hostname>

WebLogicPort <portnumber>

</Location>

b. Use the remote registration tool oamreg as follows in section 15.2.2.2:

http://download.oracle.com/docs/cd/E21764_01/core.1111/e100/osso_b_oam11g.htm#JISEC9104

15.2.2.2 - Provision with 11g Webgate
1. Acquire the tool
a. The rreg tool can be found and executed on the same box where OAM is installed. No need to un-tar.
2. Created a new UCM-Request.xml:

<OAM11GRegRequest>

<serverAddress>http://ateam-hq66.us.oracle.com:7003</serverAddress>

<hostIdentifier>UCM-INT</hostIdentifier>

<agentName>UCM-INT</agentName>

<protectedResourcesList>

<resource>/adfAuthentication</resource>

</protectedResourcesList>

<publicResourcesList>

<resource>/cs</resource>

<resource>/_ocsh</resource>

</publicResourcesList>

</OAM11GRegRequest>

3. On the command line, execute the following:

./bin/oamreg.sh inband input/UCM-Request.xml

When asked to enter the admin and password, make sure the user is part of the system store you configured for OAM (e.g testuser1/welcome1)

2. Continuing Section 5.2.3.1
Notes:

You can configure the OAM Asserter and LDAP/OVD Authenticator before installing a webgate. Once the LDAP/OVD authenticator is configured, recommend to test UCM and make sure that you can bind to a user that is created within the provider you configured.

The order of the provider’s should be as follows:

OAM Identity Asserter
The following ‘Common’ parameters should be set as:

Leave the default values for the ‘Provider Specific’ tab.

OVD Provider
‘Common’ tab:

‘Provider Specific’ tab:

Based on the backend LDAP repository, make sure that you specify the correct object class and user name attribute within the LDAP filters. In our case, we used ‘inetorgperson’ and ‘uid’ for a user object and ‘groupofuniquenames’ and ‘uniqumembers’ for groups.

3. After Installing and configuring OAM 11g……

a. Recommend installing the webgate now. No good links in the documentation to install webgate 11g. Use the following: http://download.oracle.com/docs/cd/E21764_01/install.1111/e12002/webgate.htm#CACCBCFF

Notes:
Section 20.2.4
You will need the gcc libraries. Can get them here:
http://www.oracle.com/technetwork/middleware/ias/downloads/101401-099957.html

Look for ‘GCC Libraries for Oracle Identity Federation’

Use the following cpio file to extract the gcc libraries:
cpio -idvm <cpio-file>

Section 20.4
Step 2 - Ran the command:
./deployWebgateInstance.sh –w /u0/Oracle/Middleware11.1.1.5/Oracle_WT1/instances/instance1/config/OHS/ohs1 -oh /u0/Oracle/Middleware11.1.1.5/Oracle_OAMWebgate1

Step 3 –
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/u01/Oracle/Middleware11.1.1.5/Oracle_WT1/lib

Step 5 – Ran the command:
./EditHttpConf –w /u01/Oracle/Middleware11.1.1.5/Oracle_WT1/instances/instance1/config/OHS/.ohs1

b. Next you will need to copy the artifacts that were generated in step 3 from section 15.2.2.2. Copy the ‘ObAccessClient.xml’ and ‘cwallet.sso’ located in the ‘output/UCM-INT’ directory under ‘rreg’ to the /config directory.

Webgate installation completed. Make sure that the oam managed server is running and restart the OHS server.

Trouble shooting tips:

• Cannot login via OAM – A few things to verify:

• Make sure that the LDAP Authentication Module in the OAM console is pointing to the correct data store.

• Make sure that the OVD provider in WLS matches the same OAM data store configuration.

• Login looping issue

• In some cases we see a looping issue when using IE when the time sync of off between the webgate machine and the OAM server machine.
  

• Logout not working
  • Please follow the instructions to configure UCM logout with OAM. http://download.oracle.com/docs/cd/E17904_01/doc.1111/e14770/ucm.htm#ASRLA3579

In my next post, I will continue to integrate my OAM environment to include the Image Processing Management (IPM) tool, which requires UCM.
