I am trying to find documentation for when name-mapping is required based on the Windows domain they are coming from. We have multiple domains and often times users coming in from SMB to a unix security-style volume will be mapped without name-mapping in place. Other times, it is required but it seems like it is only when they come from specific other domains.
Is there any documentation that explains when name-mapping is necessary (e.g. two-way trusts, one-way trusts, or some other factor)?
I think this topic is covered in almost all ontap versions. Following KB, does a good job in explaning this concept in short. I suggest, take a look at few kbs, and see if that answeres your queries. If not, then let us know, we will try and help you out.
