How to add user access/permission in a share folder after interforest migration.

Hi All,

I have performed interforest migration domainA.local to DomainB.local successfully using admt 3.2 . ( DomainA.local and DomainB.local are two way forest trust at this moment)

However, I have a huge problem where the share files ( Netapp ShareFile) arent accessible byuserA@domainA.local once I deleted the userA from AD or in this case I will have to decom the old server ( domainA.local ).

My question is :

1. How do I make userA@domainB.local to gain the same access and permission withUserA@domainA.local withouth having to retype / re add the user one by one. ( Right click folder ->properties-> Security tab -> add user )

2. Is there any tools that can perform the above task.

Any input would be great. Thanks in advance
