Re: (ITS#9157) return additional error code information when OPT_X_TLS_NEWCTX fails

[shawn.michael.mckinney@gmail.com]

In one of our test envs, had the path wrong in replication config for =
encryption artifacts:

*** Conf excerpt: ***
syncrepl
=E2=80=A6
tls_key=3D/opt/symas/etc/openldap/file-name.pem
***

Which gives generic error:
*** Log Trace: ***
an 27 17:25:17 sapz1a slapd[6203]: slapd starting
=E2=80=A6
TLS context initialization failed (-1)
Jan 27 17:25:17 hostname slapd[6203]: do_syncrepl: rid=3D031 rc -1 =
retrying (4 retries left)
***

Would have been helpful for the message to specify which artifact =
wasn=E2=80=99t found, the line number of the config, or some other way =
of narrowing the problem.

=E2=80=94
