Issue ID: 10353 Summary: No TLS connection on Windows because of missing ENOTCONN in socket.h Product: OpenLDAP Version: 2.6.10 Hardware: All OS: Windows Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: libraries Assignee: bugs@openldap.org Reporter: julien.wadel@belledonne-communications.com Target Milestone: ---

On Windows, the TLS connection cannot be done and we get the connection error: Can't contact LDAP server.

=> Connections are done with WSAGetLastError(). After getting WSAEWOULDBLOCK, the connection is not restart because of the state WSAENOTCONN that is not known.

OpenLDAP use ENOTCONN that is set to 126 by "ucrt/errno.h" while WSAENOTCONN is 10057L. Adding #define ENOTCONN WSAENOTCONN like for EWOULDBLOCK resolve the issue.
