Bruno,

 

OK I was able to validate my line of thought and yes you can edit the
"dynamic user" in ACS and assign him a static IP address. The caveat is that
you will need a "VPN Pool" to initially assign to the remote access user
otherwise they will not be able to login to the VPN. Because for remote
access VPN to be successful you have to assign that user an IP address.

 

Otherwise just know that they will fail when they connect the first time,
however the "dynamic user" account is still created in ACS because
technically they authenticated successfully to the AD domain.

 

Then you can edit the user account and statically assign the IP address.

Bruno,

Why don't you setup LDAP authentication on ASA instead of RADIUS? Then you
can use almost any attribute from AD. I've never tried this with IP address
but I think it may work.

example: 

ldap attribute-map MAP
 map-name  Some-AD-Attrib IETF-Radius-Framed-IP-Address

and so on...

Piotr

Well, I cannot use local database authentication and that's where I'm
stucked at. 

 

It's not practical to have all the users from the Domain created manually in
the ACS so this is not something I can do. I was wondering if it's possible
to user any Radius AV-Pair in order to extract the ip address information
from the Active-directory server somehow but I have never seen it.

 

Does anyone have an idea?

Guys, 

This is a pretty cool topic. Just wondering is this part of v4?

Still trying to grasp v4 topics.

 

Best Regards.

Hi Bruno,  

 

Are you able to authenticate via local database? If so, you can use user
attributes to assign the ip address on RA-VPN.

username <userid> attributes
vpn-framed-ip-address <ip address> <subnet mask> 

 

Hope I was helpful.

Hi guys, 

 

I hoppe you all can help me to find out a thing that's been a pain here. I'm
using dinamic user mapping from active-directory to ACS and there are some
specific users that must have a static ip address assigned to their profile
after connecting to the VPN, ok, we can do that on ACS staticly after the
user connect to the VPN because the username mapping is made and then we
assign a static ip address to it but this is been a pain because ever since
we have to  do any change to the ACS server, the dynamic mapping is gone and
then we have to rebuild this manually. 

 

I was wondering if there's anyway of doing a static ip assignment to a
dynamic user mapping. First I though on doing this with radius but I could
not find any option that allow me to do it so...Can anyone help me with
that?

 

thank you very much!
