I am trying to configure AD RMS on windows 2012 server. On a post deployment task it fails saying "one or more AD RMS role services could not be configured: AD RMS setup failed because of invalid configuration setting". So when I ran setup with some debugging option then I come to know the exact error which says "Message: The 'http://tempuri.org/RMProvisionSettingsSchema.xsd:Domain' element is invalid - The value 'D' is invalid according to its datatype 'http://tempuri.org/RMProvisionSettingsSchema.xsd:WindowsDomainName' - The actual length is less than the MinLength value."
My domain name is d.local..
Can someone has the solution for this, because nowhere is documented about the domain name length.
