Yes, that is required for IPv6 addresses in URLs.

Thanks, Howard. Just off-topic for a shot while, does this mean that when I am doing SASL binding over IPv6 address, it also must be surrounded by brackets?

ldapsearch didn't fail, the GSSAPI/Kerberos library did. It
was unable to match the provided IP address to the name of a
Kerberos server principal. In general, Kerberos requires
valid hostnames, it doesn't work well with numeric addresses.

But it can work well with numeric IPv6 addresses in simple binding. And when working with IPv4 addresss, SASL binding is also successful, coz it will initiate a reverse nslookup to find out FQDN of the LDAP server. So, why it can't deal with numeric addresses in IPv6? Kind of strange.

Is it possible that in the server, there isn't SPN for IPv6 address, but only IPv4?

That's a question for your Kerberos admin to answer.
