Before You Install the Policy Server

Be aware of the following before installing the Policy Server:

Administrator privileges—You must be logged into a Windows account with local administrator privileges to install the Policy Server.
System path length—The Policy Server installation fails if the system path length exceeds 1024 characters, including or excluding the SiteMinder added directories.
Note: We recommend trimming the pre-SiteMinder system path to approximately 700 characters for best results.
Web Server instance—Be sure that the Sun Java System or IIS Web server instance is stopped. Stopping the Web server lets the Policy Server installer configure the FSS Administrative UI to operate with the selected Web server instance.
Environment variables—The Policy Server and documentation installations each modify environment variables.
IBM Directory Server only—Using an IBM Directory Servers in your SiteMinder environment requires that you edit the V3.matchingrules file by adding the following line:
```
MatchingRules=(2.5.13.15 NAME 'integerOrderingMatch' SYNTAX 1.3.6.1.4.1.1466.115.121.1.27)
```
The Directory store will not be configured correctly and the necessary SiteMinder objects for the policy store cannot be created if the V3.matchingrules file does not contain the change.
