Identity Manager recommends you to use a secure (SSL) connection between OSP and Identity Vault. If you are using a non-SSL connection, you cannot log into the reporting application after upgrading it.
This issue occurs because the Identity Vault upgrade process sets the Require TLS for Simple Bind with Password setting to true. This setting configures Identity Vault to disallow clear passwords and other data. If you make a secure connection to port 636 and have a simple bind, the connection is already encrypted. No one can view passwords, data packets, or bind requests.
You can workaround this issue in one of the following ways:
Configure SSL between OSP and Identity Vault.
Set Require TLS for Simple Bind with Password setting to false after upgrading the Identity Vault.
