Do I want to set the database connection as an environment in order to loop through feature classes?

After mass loading a bunch of feature classes into a enterprise geodatabases (10.3.1, MSSQL),  I need to add privileges for a role to many of them.  I tested ChangePrivileges  with a single feature class,  it worked,  so now I thought I would extend this by getting a list of feature classes, then using a For loop on the list to grant the privileges.  But it didn't wok to set up the correct database connection as a env.workspace.  What's the correct way to loop through a enterprise geodatabase to add permissions?  Or do I want to do this in a totally different way?  The following script gives a TypeError: 'NoneType' object is not iterable  on debugging line 17, indicating I didn't get anything into the list.

import arcpy
from arcpy import env
env.workspace = "Database Connections/Streams as GisOwner.sde"

#get list of feature classes in geodatabase.
fclist = []
fclist = arcpy.ListFeatureClasses ("Database Connections/Streams as GisOwner.sde")

#datasetName = "Database Connections/Streams as GisOwner.sde/Streams.GISOWNER.str37_route_rivers"
#datasetName = "Streams.GISOWNER.str37_route_rivers"
#arcpy.ChangePrivileges_management(datasetName, "GISUsers", "GRANT", "AS_IS")

for fc in fclist:
    print fc
    #arcpy.ChangePrivileges_management(fc, "GISUsers", "GRANT", "AS_IS")
