Hi,
From past few days I and my few team members were getting the following error during LDAP authentication:
javax.net.ssl.SSLException: Algorithm missing:

I checked the java.security and found that all the providers are registered correctly:
security.provider.1=sun.security.provider.Sun
security.provider.2=com.sun.net.ssl.internal.ssl.Provider
security.provider.3=com.sun.rsajca.Provider
security.provider.4=com.sun.crypto.provider.SunJCE
security.provider.5=sun.security.jgss.SunProvider
I did some analysis, when i run the code from a windows batch file, it works but if i run it within Eclipse, it throws this Algorithm not found exception. i checked the JVM version and classpath and it looks okay.
I make a little program to find out whether all the providers are available during runtime or not
Provider[] provs = Security.getProviders();
In result I get only one privider and all other were missing. The jar was not getting loaded in eclipse tomcat during runtime.
For solution, I added following three jar files in tomcat boot classpath and it worked form me and my team members 
-rt.jar
-jsse.jar
-jce.jar
