Exactly -- Kepler doesn't communicate directly with LDAP -- it only communicates with the Metacat repository, which uses LDAP as its authentication provider:<div><br></div><div><font face="'courier new', monospace"> Kepler <--> Metacat <--> LDAP</font></div>

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.<br><font color="#888888">

<div>This error occurs when Kepler is unable to contact the LDAP
server that provides authentication for the Kepler
repository. It sounds as if you have a personal repository
installed? If so, then it probably means that either your LDAP
server is not working -- either its been shut down, or its
overloaded, or there is a firewall blocking access. You can test
the accessibility of the LDAP server by using the 'ldapsearch'
command line tool. If you didn't use your own LDAP and instead
are relying on ours at <a href="http://ldap.ecoinformatics.org" target="_blank">ldap.ecoinformatics.org</a>,
then the problem is likely a firewall issue, as that server
seems to be running fine. If you send more details about the
location/versions of your repository and ldap servers, we may be
able to help more with troubleshooting.</div>

I am getting an error when I try to upload a workflow to my
repository or when I try to perform Tools->Ecogrid
Authentication. I noticed uploading to my repository became
very slow yesterday evening and about 2AM EST, I became
unable to connect. I have been unable to connect since.
The error message is below. I appreciate any help you can
offer.<br>
