Clever sysadmin needed! How to keep SMB shares mounted?
Not certain I understand the context of your question, so let's try this first: 

This has worked for me: 


Mount the SMB/CIFS share using Finder's Go, Connect to Server....  
If prompted for credentials, and given the option, store those credentials in the Keychain
Open System Preferences, Users and Groups; select the Login Items tab near the top 
Click the + button at the bottom of the list of login items to "add" an item. 
This will produce a new Finder window that allows you to select an item. Simply navigate to the mounted SMB/CIFS share from the Sidebar, select/highlight the SMB/CIFS share of interest, then click the Add button in the bottom right of the Finder window. 


This should dismiss the Finder window, and now the share should be mounted at each login. Let us know if this doesn't work/isn't what you needed.
