Specifying an LDAP URL for Authentication
To specify an LDAP URL to use as the basis of authentication from PTC HTTP Server, issue the following command. The command string must be entered on one line:
PTC HTTP Server
ant -f webAppConfig.xml addAuthProvider -DappName=<Web application name> -DproviderName=<LDAP provider Name> -DldapUrl=<LDAP URL>
This command can be used to add additional LDAP URLs for authentication.
To add users to the LDAP, consult the Windchill Directory Server Administration Guide.
