Thanks for attention and excuse me that occupied your time.
The problem was in CRL generated by EJBCA. Apparently, EJBCA and openSSL
is not entirely compatible. When I remove CRL distribution point field
from my
EJBCA generated CRL, all works as expected: valid certificates accepted,
certificates rejected. And no problem with CRL scope, so fix from first
reply doesn't
needed, all works with initially installed openssl-1.0.1c

With regard to apache I think it checks certificate validity with OCSP.
And I doesn't embed CRL in ca certificate for apache.
Perhaps it would be nice to implement OCSP validity checking together with
embedded CRL with possibility to choose which one will be used.

Thanks again, especially for a hint about openssl scope loop problem.

With best regards, Alexey Prokopchuk (AP8686-RIPE)
