For this error post install trying t log into the management console:
"It seems to be a configuration error, no users have been granted access right to the directory"
Here is what I found in the knowledge base:
Disabled native authentication in the Management Console setting the Enable
parameter for ManagementConsoleAuthFilter to false in the <im-install>\
iam_im.ear\management_console.war\WEB-INF\web.xml file and restarting IM. Could
then access the Management Console in order to reload directory xml files. To
then reenable native authentication, also needed to add attribute MEMBER_RULE to
the IM_DIRECTORY_LD table with user configured in IM_AUTH_USER.
