<p>Hi Jacky,</p>
<p>OpenSIPS will always require you to configure a client
certificate for TLS client domains and will also present
that certificate when connecting. But normally, a TLS
server can simply choose not to verify the client
certificate. I don't have any experience with AWS RDS
though but it seems odd to not accept a connection only
because the client did present a certificate.</p>

<div>Hi Bogdan-Andrei,</div>
<div><br>
</div>
<div>I checked the mariadb documentation and found
mariadb has two options to set ssl connection: two-way
TSL and one-way TSL. It seems AWS RDS only supports
one-way TSL, that is, TSL is used without a client
cert. Does OPENSIPS support such one-way TSL to
connect a database? Thanks!</div>
