Virtual Access Interface not cloned from Template

I have an issue with Virtual Profiles running on an AS5300, 12.1(20) with
CSACS 2.6 as the TACACS+ authenticatio mechanism. The access server serves
dial-up users (via a group-async interface) and ISDN dial-in users using
fixed static dialer profiles. I am trying to extend this to use virtual
profiles for some ISDN dial-in users (to principally download access-lists
and routes on a per-user basis).

However, after configuring virtual templates, the virtual access interface
is not cloned.

Are any special AAA authorization parameters required on the user's CSACS
configuration?

Presumably the PPP authentication/authorization configuration used to
authenticate the user, as the details configured on the physical serial
interface.

ISDN Caller ID is used to bind inbound calls to the physical dialer
profile, but the users without static dialer profiles have an ISDN caller
statement under the physical interface, so the call is not rejected.

The user is authenticated and authorized but the virtual template is not
cloned.

The relevant parts of the configuration are:

aaa new-model
aaa authentication login default local
aaa authentication login TELNET line
aaa authentication login DIALINPPP group tacacs+ local
aaa authentication ppp default local
aaa authentication ppp ROUTERPPP local
aaa authentication ppp DIALINPPP if-needed group tacacs+ local
aaa authorization exec DIALINPPP group tacacs+ if-authenticated
aaa authorization network ROUTERPPP if-authenticated
aaa authorization network DIALINPPP group tacacs+ local
aaa accounting network DIALINPPP start-stop group tacacs+
