Yeah, I tried isql as the mysql user. This worked just fine:

sudo -u mysql isql connect_test_azure UID PWD

That suggests to me that the mysql user can read all of the
configuration files no problem.

Since you mentioned SELinux, I just now set it to permissive mode, and
now the CONNECT engine can connect to the data source with no issues.
I guess SELinux doesn't want /usr/sbin/mysqld to make outgoing TCP
connections. /var/log/messages shows:

Feb  4 18:56:17 localhost python: SELinux is preventing
/usr/sbin/mysqld from name_connect access on the tcp_socket .

If you want to allow mysql to connect any
Then you must tell SELinux about this by enabling the
'mysql_connect_any' boolean.
You can read 'None' man page for more details.
setsebool -P mysql_connect_any 1

If you believe that mysqld should be allowed name_connect access on
the  tcp_socket by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep mysqld /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Thanks for the help!
