F5 APM SAML IDP : does someone use transient ou persistent name-id format ?

Hello,

 

With v12, we can configure BIG-IP APM SAML as IDP to use persistent ou transient name-id format, but the problem is to choose an opaque value (not the same for different SP, and no information to identity the user).

 

SAML products provide generators to calculate this opaque value. I don't find generator in BIG-IP APM.

 

Does someone use APM IDP with transient or persistent format, and then how do you generate the value ?
