During installation, if the user attempts to point OpenAM at either a Data Store, or User Store that does not have the Base Entity created you will get the cryptic error message "Invalid Suffix" and the installer will hang.
This error message is not informative enough to guide the user to the correct resolution of the problem.
Some alternative text would be preferred such as:
"Invalid Suffix for OpenDJ server <hostname>:<port>. No Base Entity found."
This would guide the user to the correct location to resolve the problem.
