Bug #80442	mysql_real_connect using SSL throws 1045 Access denied for user

Tags:	mysql_real_connect mysql_ssl_set

Description:
Cannot authenticate using SSL when using Connector/C 6.1.6. Disabling SSL gives expected access. Using Connector/C <= 6.1.5 works well for both SSL and non-SSL.
User grant is "REQUIRE NONE", but changing to "REQUIRE SSL" does not help either.

Tried compiling using both yaSSL and OpenSSL, but seems issue is the same regardless.

Mysql server version is 5.6.28.

How to repeat:
Use Connector/C 6.1.6 and enable client to use SSL.

# (compile program with mysql_ssl_set)
# export LD_LIBRARY_PATH=/usr/src/mysql-connector-c-6.1.6-src/libmysql
# ./mysql-ssl-test 
Real connect: 1045: Access denied for user 'user'@'10.10.10.10' (using password: YES)

# export LD_LIBRARY_PATH=/usr/src/mysql-connector-c-6.1.5-src/libmysql
# ./mysql-ssl-test 
SSL cipher used: DHE-RSA-AES256-SHA 
Thread ID is: 62082422 

# (recompile program without mysql_ssl_set)
# export LD_LIBRARY_PATH=/usr/src/mysql-connector-c-6.1.6-src/libmysql
# ./mysql-ssl-test 
SSL cipher used: (null)

Hello Tobias Lindgren,

Thank you for the bug report.
I tried to reproduce the issue at my end using MySQL Connector / C 6.1.6 with mysql_ssl_set() but not seeing any issues to connect MySQL database.
Could you please provide repeatable test case (like sample test case. - please make it as private if you prefer) to confirm this issue at our end?

Thanks,
Chiranjeevi.
