Description Joe Orton 2018-02-23 12:21:40 UTC

Description of problem:
Per bug 1493181, the OpenSSL internal X509_NAME comparison function for SSL_* is case insensitive; this prevents adding CA names which differ in case.  An example of public deployment of such CA names is known.

Version-Release number of selected component (if applicable):
openssl-1.0.2k-8

How reproducible:
always

Steps to Reproduce:
1. create cert bundle with cert subject names which differ only in case
2. call SSL_load_client_CA_file() on that bundle 

Actual results:
certs differing in case in subject are treated as duplicates and one is ignored

Expected results:
both certs differing in case in subject name added to X509_NAME stack
