Bug#14211069: CRASH WHEN REWRITING GRANT STATEMENT CONTAINING "REQUIRE ISSUER"

Tatjana Azundris Nuernberg · Tatjana Azundris Nuernberg · commit 85bcd049dc01 · 2012-06-20T15:30:00.000+01:00
Issuer in X.509 info was not rewritten correctly. (X.509 info used for actual 
connections was correct, but the issuer in a statement rewritten for logging
would be wrong.)
