[cifs-protocol] [REG:120080321001822] LDAP connections have hard timelimit of one hour?

[Obaid Farooqi]

Hi Metze:
This information that you provided is not sufficient to figure out what is happening from the server side that is causing client to issue error. Can you please provide more details and possibly a network capture?

Hi Metze:
In case of Windows-Windows, error 52 is generated by the client side (server does not generate this error). How and where you are getting this error?

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!
