If the Apache Manager Daemon Install or the Apache Manager daemon is having trouble connecting to the LDAP server, check each of the following possible causes:
Verify that the JVM* is installed correctly. You must use Java 2, version 1.3.1 or later, and the path to the java.exe needs to be correctly identified.
Verify that the LDAP server is running.
If the daemon is producing a certificate exception, you might need to run the Key Import Wizard. To do so, open the apacheadmin\lib\KeyImport.bat batch file in a text editor and verify that the last line in the file includes the correct name of your LDAP server and the secure port used by it. Then run the batch file.
The Key Import Wizard imports the LDAP server's certificate into Java's default key store. The Apache Manager daemon can then make a secure connection to the LDAP directory.
Open the apacheadmin\conf\startup.properties file and verify that the LDAP server and LDAP port information is correct. Also, verify that the administrator username and all other settings are correct.
