[kepler-dev] LDAP Authentication Error

[Scott Zimmer]

Matt,

Thank you for the troubleshooting help.  I checked our private 
repository and noticed that it had rebooted and the tomcat server did 
not restart when it rebooted.  When I brought our repository back up, I 
can now successfully authenticate.  I didn't realize the repository had 
to be up in order for me to authenticate against the LDAP server.  I 
guess the configuration files in Kepler show where the repository is 
located and the configuration files in the repository specify the LDAP 
server location.
