18 Oracle Application Server Single Sign-On

18.1.1.1 Update the mod_rewrite Entry for SSO

Take the following steps:

1. Back up the sso_apache.conf file:

   cp ORACLE_HOME/sso/conf/sso_apache.conf   
       ORACLE_HOME/sso/conf/sso_apache.conf.BACKUP
   
   

2. Edit the file. Locate the mod_rewrite entry that contains the following text:

   <IfModule mod_rewrite.c>
       RewriteEngine On
       RewriteRule ^/pls/orasso/orasso.wwsso_app_admin.ls_login$ /sso/auth [PT]
   </IfModule>
   
   

   Add the following line:

   RewriteRule ^/pls/orasso/orasso.home$ PROTOCOL:
       //LBR_HOST:LBR_PORT/pls/orasso/orasso.home [R,L]
   
   

   replacing the placeholders in italics with the following values:

   • Replace LBR_HOST with the full hostname for the HTTP load balancer.

   • Replace LBR_PORT with the SSL listening port. If SSL is enabled, enter the SSL port value. If using the default ports of 80 or 443, do not specify a port value.

   • Replace PROTOCOL with either HTTPS (if using the SSL port) or HTTP (if using the non-SSL port).

     For example, the entry might look like this when using a nondefault SSL port:

     <IfModule mod_rewrite.c>
         RewriteEngine On
         RewriteRule ^/pls/orasso/orasso.wwsso_app_admin.ls_login$
             /sso/auth [PT]
         RewriteRule ^/pls/orasso/orasso.home$ https:
             //lbr.mydomain.com:4443/pls/orasso/orasso.home [R,L]
     </IfModule>
     
     

     As another example, the entry might look like this when using a default SSL port:

     <IfModule mod_rewrite.c>
         RewriteEngine On
         RewriteRule ^/pls/orasso/orasso.wwsso_app_admin.ls_login$ 
             /sso/auth [PT]
         RewriteRule ^/pls/orasso/orasso.home$ https:
             //lbr.mydomain.com/pls/orasso/orasso.home [R,L]
     </IfModule>
     
     

3. Save and close the file.

4. Restart Oracle HTTP Server.

18.1.1.2 Update targets.xml

The following configuration steps are needed only in the installation scenario where communications between clients and the load balancer use HTTPS, and communications between the load balancer and Oracle HTTP Server also use HTTPS:

Client ---[HTTPS]---> Load Balancer ---[HTTPS]---> Oracle HTTP Server

In this case the oracle_sso_server entry in the targets.xml file, on each physical host of the cluster, must be reconfigured to monitor the local SSL port.

Perform the following steps to update targets.xml on each node of the cluster:

1. Back up the targets.xml file:

   cp ORACLE_HOME/sysman/emd/targets.xml 
       ORACLE_HOME/sysman/emd/targets.xml.BACKUP
   
   

2. Open the file and find the oracle_sso_server target type. Within this target entry, locate and edit the following two attributes:

   • HTTPPort - the server SSL port number

   • HTTPProtocol - the server protocol, which in this case is HTTPS

     For example, you could update the two attributes this way:

     <Property NAME="HTTPPort" VALUE="4443"/>
     <Property NAME="HTTPProtocol" VALUE="HTTPS"/>
     
     

3. Save and close the file.

4. Reload the OracleAS console:

   ORACLE_HOME/bin/emctl reload
