Hi, Andreas has pointed out that my personal os.bias module has prevented me from producing pythonically correct code. Please note the replacement of z1[:-1] with z1.strip() below. Then an external method (LoadUsers) to read it: def LoadUsers(self): f=open('/var/lib/zope/Extensions/usr_pwd.txt', 'r') y=f.readlines() return y And a script (user_load): ## Script (Python) "user_load" ##bind container=container ##bind context=context ##bind namespace=_ ##bind script=script ##bind subpath=traverse_subpath ##parameters= ##title= ## y=context.LoadUsers() p=[] for x in y: z=x.split(' ') z0=z[0] z1=z[1] z1=z1.strip() acl = container.restrictedTraverse( '/foobar/acl_users' ) acl.userFolderAddUser( z1, z0, p, '' ) return 0 Sean
