</div>We have a set of other use cases which are around the use of the server name to get a Kerberos/X.509 identity which imposes other restrictions on the name being chosen (such as maximum length and limited set of characters). The unique name is one scenario but there are others.<br>
<br>
Thus, we could start adding new options such as "max server name length" and "server name character set" or we find a way to do a plugin.<br>
