Answer 1

Based on what I think I understand in this reply it appears that the problem is caused in the named authorization method of T-AUTHOR. This named method sends an authorization request to the TACACS server. So it appears that the TACACS server is not authorizing the commands that you enter.
I would suggest this as a first test:
- login to the device.
- go into enabl mode.
- attempt the show run command. (I assume that it will fail)
- check on the TACACS server. look in the logs for indications of how it processed the request and why it did not authorize it.
If you want to do a second test to verify the cause of the problem then I would suggest this:
- remove from the config these lines
aaa authorization exec T-AUTHOR group tacacs+ if-authenticated
aaa authorization commands 15 T-AUTHOR group tacacs+ if-authenticated
then login to the device, go into enable mode, attempt the show run command
Try one or both of these tests and post back to tell us of the results.
