Good day.

I have what may be a simple question that I am just missing or not asking correctly.  I know that it is easy to add a custom value for user profiles.  But I was wondering if you can do the same at the portal level?  -  Some options I have thought about was using the copyright field or adding a column to the portal alias table but I know that could/would break upon upgrade and I would rather not mess with the core components as I am not sure what would break.

But what we are looking to accomplish is that I have a custom homegrown system that DNN uses to grab validate users against for their registration.  They are first loaded into the backend system and then given the information to login to a specific portal.   however as I move from our dev, to stg, to uat, to prod envs the portal number may not be consistent, so I can't use that, the home directory could change, and the URL does change.  (dev.mysitea.com stg.mysitea.com and then www.mysitea.com)  so I am trying to find a way to add a value to the site that gives it the code to validate the user during the registration process to make sure that the user is registering from the correct portal into our back end system.  portal A will always have a code of abcd, portal b would always have the code of 1234.  But this would not be known to the user.

So with my limited thinking, the easy thing would be to add a column to the portal alias table, and store abcd for portal a and 1234 for portal b.  When the user registers and we look back at the URL they are coming from and then the portal alias table / grab the additional column value/ and then pass it to our custom database it will pass their entry code and abcd or 1234   If their code and value matched great if not I could return an error back.

Is there a better way then adding a column to the portal alias table?  I don't see a way to add a field to  the portal level like i do for users...

thank you!
