Yes, only one can be created via the Scan to Home option, if you want PDF vs Tiff you would either have to change those options in the template at the time of scan, or setup templates to go to the scan to home location manually in the Scan templates. (LDAP does not transfer, the scan to home location is going to be either FTP, or an SMB share, it is just settings that are provided to the device via LDAP)
To find where your Scan to Home files are going and what Protocol they are using you can just search a user in CWIS via
Properties > Connectivity > Setup > LDAP > Edit and select User Mappings then search a user.
So basically, on all devices Scan to Home will be one template. If you want more than one template you need to create them manually.
The beginning of the Home location is your clue to its protocol, \\ is an SMB share, / is FTP
