multiple instances of pam module

Hello everybody,

Is there a way to include multiple instances of the pam module in the radius?
We are currently using a freeradius 2.2.8 with several virtual servers.
Two services are to be secured by a 2-factor authentication (Google Authenticator).
1. Login VMware HorizonView (desktop-virtualization)
2. IPsec VPN connection

VMware Horizon expects a login with username and passcode with a subsequent query of the password.
For the login of the VPN connection the password + passcode is expected together in a field.

Attempts to integrate several instances (similar to the file or ldap module) within the pam module do not work.
I am thankful for every hint.
Thanks in advance.

Best regards
Lars Hillebrand



 - Content of /etc/freeradius/modules/pam

pam {
        pam_auth = radiusd
}
pam 2facaut_pam {
        pam_auth = 2facaut_pam
}
pam horizon_pam {
        pam_auth = horizon_pam
}


- Contents of the individual pam files from /etc/pam.d/

# /etc/pam.d/horizon_pam - PAM configuration for FreeRADIUS
auth requisite pam_google_authenticator.so forward_pass try_first_pass
auth    [success=2 default=ignore]      pam_unix.so nullok_secure
auth    [success=1 default=ignore]      pam_ldap.so use_first_pass

# /etc/pam.d/2facaut_pam - PAM configuration for FreeRADIUS
auth required pam_google_authenticator.so forward_pass
auth required  pam_ldap.so use_first_pass

- Here the debug log with separate horizon_pam configuration in the radius
