Login params are a configuration value. Just like all the other 4000 configuration values. It's a value used to determine what to do at a branch point: which decryption method do I use? which parsing method? what's the timestamp window? what's the home page? This is classic control table technique.

So your suggestion now is to just store bridge login parm values in the client table? Where do you draw the line? Why not the client's account control parms, or their routing parms?
