Using TACACS+ auth from ACS 5.1.0.44 to ACE. Having Issues with Shell (Exec)

Question

Using TACACS+ auth from ACS 5.1.0.44 to ACE. Having Issues with Shell (Exec)
So I am trying to get TACACS+ auth to work for my ACE.
The command string that I have on the ACE is as follows:
tacacs-server host 172.16.101.4 key 7 XXXYYYZZZ timeout 15
aaa group server tacacs+ tacacs+
  server 172.16.101.4
aaa authentication login default group tacacs+ local
aaa authentication login console local
aaa accounting default group tacacs+ local
But to finish getting this enabled I need to create some sort of shell (exec) string in the ACS that tells the ACE what permission level to allocate.
I do not know how to do this on the ACS 5.1.0.44.
Anyone know?
TAC made a good suggestion but the command path doesn't seem to line up with my version of ACS.
Thanks for your reply. About this question:
shell:<Context>*<Role> <Domain>
What I meant is that you need to check the following couple of things on
your ACS server in order to have AAA Tacacs users to login into the
ACE over the context with superuser ritghts.
Group setup ‑> users ‑> TACACS + Settings ‑> enable Shell(exec)
‑> enable Custom attributes ‑> right below this part you need to
use the following sintax to link the ACE context that this user
has access to.
For example:
shell:<Context>*<Role> <Domain>
shell:Admin*Admin default‑domain
Where this user will have access to the Admin context with the role
admin using the 'default‑domain'

Wilfred,
What you will have to do on your version of ACS is modify the shell profile that your admins are hitting for other IOS devices or you can create another shell profile under Policy Elements -> Device Administration ->
Once you get into this shell profile select the Custom Attributes tab and put in the following fields close to the bottom of the screen, from the example you provided type shell:Admin for the attribute field and then default-domain for the value field, and make sure you select this requirement as optional, if you select mandatory and other IOS devices use this same shell profile you will force this av pair to these devices also which will impact the priv levels that then need for authentication.
After you add this attribute, save your changes and then test, also make sure that your Aceess Policy is calling this shell profile under the authorization profile for default device admin.
Thanks,
