Answer 1

You can obtain the same result by doing this (context.Identity is the previous identity):

OnValidateIdentity = context => SecurityStampValidator.OnValidateIdentity<ApplicationUserManager, DtbsUser, Guid>(
                            validateInterval: TimeSpan.FromSeconds(30),
                            regenerateIdentityCallback:
                                (manager, user) =>
                                    user.GenerateUserIdentityAsync(manager, context.Identity),
                            getUserIdCallback: (ci) => Guid.Parse(ci.GetUserId())).Invoke(context)

Answer 2

I gave up and created own SecurityStampValidator which does exactly the same as original, but passes the current claimsIdentity to regenerateIdentityCallback as param. Not at all happy about this solution, but it works.

       OnValidateIdentity = MySecurityStampValidator.OnValidateIdentity<ApplicationUserManager, DtbsUser, Guid>(
                    validateInterval: TimeSpan.FromSeconds(10),
                    regenerateIdentityCallback: (manager, user, previousIdentity) => user.GenerateUserIdentityAsync(manager, previousIdentity),  
                    getUserIdCallback: user => Guid.Parse(user.GetUserId()))
