I am sorry. Let me clarify the question. In our environment we have to multi domain names that our new filers will have to serve CIFS volumes & datastore volumes for our VMware. Multi domain names, such as TEST.example1.com Prod.example1.com UAT.example1.com.
My question is without creating multi SVMs for each domain, is there a way to implement/serve multi domain CIFS volumes without having to create additional SVM?
Each vserver can only authenticate within one domain.
From the man pages:
The vserver cifs create command creates a CIFS server on a Vserver. When you create the CIFS server, you must add it to an existing CIFS domain. When you enter this command, the storage system prompts you to provide the credentials of a user account that has sufficient privileges to add computers to the -ou container within the -domain domain. The user account must have a password that cannot be empty. If the new CIFS server is joining a domain, this command might take several minutes to complete.
Small note here - if your domains have trust between at least so that the domain where the SVM is trusts the domain where the user is. you will be able to authenticate in a cross domain manner. (of course the objects such files and folder will need to have an ACL allowing this user or member groups the access to the object)
