#9 JPAM crashing
We are using net.sf.jpam.Pam to authenticate the user-name and pwd with the script, having the content:
. /opt/tpa/etc/tpautils.sh
Setup environment variable needed to fine PAM shared object
LD_LIBRARY_PATH=$TPA_HOME/lib
export LD_LIBRARY_PATH
JAVA_OPTS="-Djava.library.path=$TPA_HOME/lib"
CLASSPATH="$JBOSSHOME/common/lib/JPam-1.1.jar"
CLASSPATH="$CLASSPATH:$JBOSSHOME/common/lib/commons-logging.jar"
"$JAVA_HOME/bin/java" $JAVA_OPTS \
-classpath "$CLASSPATH" \
net.sf.jpam.Pam "$1" "$2"
From the last two days, the script is crashing.

Hi
Issue is resolved. The lib "net.sf.jpam.Pam" was crashing as the password was going to be expired. A warning was coming for the password, we reset the password and now issue is resolved. Any plan to have the correction in the coming release.
Thanks once again..
Regards
Asif
