 * `ssl_enforcement_enabled` - (Required) Specifies if SSL should be enforced on connections. Possible values are `true` and `false`.
 
+-> **NOTE:** `ssl_minimal_tls_version_enforced` must be set to `TLSEnforcementDisabled` when `ssl_enforcement_enabled` is set to `false`.
+
+* `ssl_minimal_tls_version_enforced` - (Optional) The minimum TLS version to support on the sever. Possible values are `TLSEnforcementDisabled`, `TLS1_0`, `TLS1_1`, and `TLS1_2`. Defaults to `TLS1_2`.

 * `storage_mb` - (Optional) Max storage allowed for a server. Possible values are between `5120` MB (5GB) and `1024000`MB (1TB) for the Basic SKU and between `5120` MB (5GB) and `4096000` MB (4TB) for General Purpose/Memory Optimized SKUs.

 * `tags` - (Optional) A mapping of tags to assign to the resource.
