* RECOMMENDATION:                                              *
****************************************************************
In the Liberty OpenID Connect Provider feature, if the
idTokenLifetime setting is in the range of 25 days (600 minutes,
or 2160000 seconds) or more, the idToken's expiration (exp)
value is set to less than the issued at (iat) value.  The exp
value should always be greater than the iat value.

When you trace the OP, you'll see something similar to:

aud=oidcclient, exp=1516419728, iat=1518122696}

Problem conclusion

The OpenID Connect Provider feature is updated to always set the
idToken expiration (exp) to a value that is greater than that of
the date and time it was issued (iat).
