Go to Interface Configuration > Advanced TACACS+ Settings.

Check Advanced TACACS+ Features in Advanced Configuration Options and click Submit. This will make the Advanced TACACS+ Settings visible under the user configuration.

Under IOS authorization permit all unmatched commands on the ACS and also permit all attributes. Also make sure shell (exec) is enabled and priviledge level is 15 for the user
