[cifs-protocol] LDAP connections have hard timelimit of one hour?

[Stefan Metzmacher]

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)
     extendedResp
     resultCode: unavailable (52)
     matchedDN:
     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?

Thanks!
