Tacacs Authentication - VRF ?

Question

Hi !
Our Management LAN for accessing the switch is reachable through a VRF.
I tried to configure TACACS+ for User Authentication - by specifying "ip tacacs source-interface vlxxx".
This vlxxx is member of this Managment-VRF.
But the switch does NOT send any TACACS request through that particular VRF.
Could you plz help me ?
thx
Hans

I'm having the same issue with a router running: c2800nm-advipservicesk9-mz.124-15.T1.bin
The config is as follows:
aaa new-model
aaa group server tacacs+ TACACSGROUP
server-private 10.1.2.49 port 49 key 7 143A070718xxxxx26616572000156
ip vrf forwarding XXXX-General
ip tacacs source-interface GigabitEthernet0/0.9
aaa authentication login default group tacacs+ local
aaa accounting exec default start-stop group tacacs+
