Thanks! Note the lifetime of the krb5 service tickets seems to be 1
hour, maybe that's related.
For SMB2 connections there's also a relationship to the lifetime of the
krb5 service ticket, before the server starts returning
Maybe the LDAP server is doing something similar.

> Hi DocHelp,
> I just debugged a problem where a Windows AD DC send the following message after exactly 1 hour:
> LDAPMessage extendedResp(0) (The server has timed out this connection)
> messageID: 0
> protocolOp: extendedResp (24)
> resultCode: unavailable (52)
> errorMessage: The server has timed out this connection
> The connection was used at least every minute and the last success was returned 2 seconds before this.
> These are Windows 2019 DCs, is this special to them, or does this happen with any Windows Version?
> I can't find anything related in [MS-ADTS]
> Can you clarify this?
