Update SAML attributes

Hello,

 

I would like to know if it's possible to update a SAML attribute on an existing session when the F5 is used as IdP.

 

Here is the scenario:

 

1 - User ask to login in SP-A.

 

2 - He gets redirected to the IdP (F5), login, gets a saml assertion and get back to SP-A.

 

3 - User go to another SP-B and ask to connect.

 

4 - He gets redirected to the IdP, as he already have a session, the F5 redirects him back to SP-B with the saml assertion.

 

One of the saml attribute is drived from a session variable, and this variable will change when the user goes to SP-B. The problem is that the attribute value is not updated in step 4.

 

Any idea how to solve this issue?

 

Thanks.
