The installation process for the filter is very similar to Installing the Sentinel VoLTE Provisioning Module, with some changes for the Sentinel Authentication Gateway.

For completeness, the entire process is described here.

Note The Sentinel VoLTE Provisioning module is part of Sentinel VoLTE and includes the Sentinel VoLTE XCAP server. Check the Sentinel Authentication Gateway Compatibility Guide for the required version of REM, installed with Apache Tomcat.

Prerequisites

You’ll need these files to install the Sentinel VoLTE Provisioning module:

apache-tomcat-<version>.zip
rhino-element-manager-<version>.zip
sentinel-volte-element-manager-<version>.jar
sentinel-gaa-em-<version>.em.jar

Below are steps to:

Set up Tomcat

See Running REM on Apache Tomcat in the REM Guide.

Tip See the Tomcat 8 - SSL How-To docs for help setting up SSL in Apache Tomcat.

Install the REM plugins

To install the REM plugins for the Sentinel VoLTE Provisioning and NAF Authentication Filter modules:

1

Copy sentinel-volte-element-manager-<version>.jar and sentinel-gaa-em-<version>.em.jar into apache-tomcat-<version>/rem_home/plugins.

2

Edit the Filter Configuration if necessary.

Customize plugin logging

1

Edit log4j2.properties with this content:

rootLogger.level=INFO
rootLogger.appenderRef.console.ref=CONSOLE
rootLogger.appenderRef.file.ref=FILE

appender.CONSOLE.type = Console
appender.CONSOLE.name = CONSOLE
appender.CONSOLE.layout.type = PatternLayout
appender.CONSOLE.layout.pattern = %d{ABSOLUTE} %-5p <%t> [%c] %m%n

appender.FILE.type = RollingFile
appender.FILE.Name= FILE
appender.FILE.filename = ${rem.home}/rem.log
appender.FILE.layout.type = PatternLayout
appender.FILE.layout.pattern = %d{yyyy-MM-dd HH:mm:ss,SSS} %-5p <%t> [%c] %m%n

logger.rem.name=rem
logger.rem.level=INFO
logger.openjpa.name=openjpa
logger.openjpa.level=INFO
logger.wink.name=org.apache.wink
logger.wink.level=INFO

# Logging from NAF authentication filter
logger.gaa.name=sentinel.gaa
logger.gaa.level=INFO

# Uncomment for subscriberdata cache eviction logging
#logger.subscriberdatacache.name = rem.server.sentinel.subscriberdata.cache
#logger.subscriberdatacache.level = TRACE

logger.audit.name=sentinel.audit
logger.audit.level=INFO
logger.audit.additivity=false
logger.audit.appenderRef.audit.ref=AUDIT

appender.AUDIT.type = RollingFile
appender.AUDIT.name = AUDIT
appender.AUDIT.fileName = ${rem.home}/sentinel-audit.log
appender.AUDIT.layout.type = PatternLayout
appender.AUDIT.layout.Pattern = "%d{yyyy-MM-dd HH:mm:ss,SSS}", "%c{1}", %m%n
Tip See Configuring NAF Authentication Filter logging for more information on logging configuration.

Import Rhino trust certificate

This can also be done using the REM web UI.

1

Import a Rhino Trust Certificate into REM:

"${JAVA_HOME}/bin/keytool" -importcert -file ${RHINO_HOME}/rhino-trust.cert -keystore "${TOMCAT_HOME}/rem_home/rhino-ems.ks" -storepass changeit -noprompt

Restart Tomcat

To restart Tomcat (as needed), run these commands:

cd $TOMCAT_HOME
./bin/catalina.sh stop
./bin/catalina.sh start
Tip Use catalina.sh run to run Tomcat in the foreground. This can be useful for debugging.
