Dear All,       Thanks for your valuable inputs. Finally I did work around and fix the issue. However it could be fit for mid-range environment. The fix is as follows:- 1. Create the folder under file system explorer "/ifs/data/Prod" 2. Create sub-folder under "/ifs/data/Prod/project" and "/ifs/data/Prod/dev" 3. Create SMB export "prod" with the export path "/ifs/data/Prod" 4. Login as root to the ision by accessing this "prod" share -  \\isiloncluster\ifs\ 5. Go to properties of "/ifs/data/Prod" folder, go to security tab and add the customer admin user with full permission and other end users [usera, userb]. Then click "Advanced" tab , Select "Change permission", Select/Edit the user "usera" with "Traverse" permission in "Allow" and the rest all permission in "Deny" column, also Keep "Apply to" should be "This Folder, Sub Folder and Files" , but assign full permission for them in the subfolder "/ifs/data/Prod/project" and "/ifs/data/Prod/dev" respectively. To achieve the subfolder full permission for usera & user b go to properties of "/fis/data/Prod/project" and "Advanced" --> "Change Permission" ---> Add "usera" and set full permission in the "Allow" column as required. 6. Here I took usera as an example, in customer environment it could be "group" permission but the procedure is same. 7. Now the challenge is here as long as the business unit grows it is very difficult to follow the same however if the BU is medium size and you are using "group" permission to manage users then this could help you.  ***********So I am marking this discussion as correct answer. ******** However I would appreciate that if any one tried the same and share us the feedback that is great..            Thanking to all and if any one need more information on this please let me know. I have screen shot for the above mentioned but don't know how to upload here.      thanking again to all.
Dear All,             I need help on the following:- Parent folder:- /ifs/data/projects Subfolders:- /ifs/data/projects/engg, /ifs/data/projects/dev Users:- usera,userb,userc SMB Export Name:- smb1 SMB Export Path:- /ifs/data/projects SMB Export/Share Permission:- Administrator -Full access, Everyone - Read access  Requirements:- end "usera" should able to access "/ifs/data/projects/engg". it doesn't work since "usera" does not have any permission in "/ifs/data/projects", but he is having full access in "/ifs/data/projects/engg".  Error:- "usera" dose not have enough privileges. So I tried like changing export path from "/ifs/data/projects/" to "/ifs/data/projects/engg" and it works. But customer does not want to export "/ifs/data/projects/engg", since they have many-many subfolders with different end user permissions. So they want to export only:- /ifs/data/projects & usera, userb should able to acces /ifs/data/projects/engg.  Please let me know if any one come across the similar situation and if any idea/solution for this. please share me the same.  Thanks in advance.
