Cisco AAA Authentication issues

The devices in question are stand-alone cisco switches.

I have attached the "debug aaa **" output below for a successful and unsuccessful login attempt. These logs come from the two switches running the same IOS & model.

I am able to authenticate with rsa token, but able to authenticate via local user database when the "aaa authorization exec if-authenticated" command is present.

If the command is not present, I am able to login via the local user database, but not radius.

Any thoughts? What additional information can I provide to help isolate this?
aaa.pass.txt
aaa.fail.txt

I think you may have an issue with the authorization config on the radius server.
According to this:

The aaa authorization exec default group radius if-authenticated command configures the network access server to contact the RADIUS server to determine if users are permitted to start an EXEC shell when they log in. If an error occurs when the network access server contacts the RADIUS server, the fallback method is to permit the CLI to start, provided the user has been properly authenticated.

the existence of the "if-authenticated" command provides a fallback to CLI if the radius is missing authentication info.
