APM local user database and OTP

You can't add additional fields, but here's a thought. The group memberships section is really just arbitrary text, so you could add strings (as groups) like the following:

sms_123_456_7890

And then read them from the policy or iRules.

when ACCESS_ACL_ALLOWED {
    log local0. [ACCESS::session data get session.localdb.groups]
}

** where "session.localdb.groups" is the destination session variable in the VPE Local Database agent.
