This issue occurs only if the following conditions are met:
Your configuration data store is Sun Java System Directory Server.
You are trying to perform a multi-server installation.
Your amadmin password is different from the Directory Server bind dn password.
Workaround. There are two parts to this workaround:
Make sure your configuration Directory Server bind dn password is same as the amadmin password.
Configure the second and additional OpenSSO Enterprise servers. To perform the second server installation and point to the first OpenSSO Enterprise server's configuration directory, simply access the Configurator page of the second OpenSSO Enterprise server and enter the amadmin password, cookie domain, and other details for Step 1 and Step 2.
For Step 3, do not select the Add to Existing Deployment. Instead, select the first instance option and provide the same Directory Server name, port, DN, password, and encryption key of your first server. Then, proceed with the configuration as usual.
