From 2585d6d6455d7c9257a8bbc65cc489d4a424a08e Mon Sep 17 00:00:00 2001 From: Alexander Bokovoy Date: Wed, 5 Aug 2015 21:33:45 +0300 Subject: [PATCH] Fix selector of protocol for LSA RPC binding string For Windows Server 2012R2 and others which force SMB2 protocol use we have to specify right DCE RPC binding options. For using SMB1 protocol we have to omit specifying SMB2 protocol and anything else or otherwise SMB1 would be considered a pipe to connect to. This is by design of a binding string format. https://fedorahosted.org/freeipa/ticket/5183 Reviewed-By: Tomas Babej --- ipaserver/dcerpc.py | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/ipaserver/dcerpc.py b/ipaserver/dcerpc.py index c604fa3eae4cf94d719190a5a3e3de15d3841d24..74b4743d4bfb9c4950f441f1aa3561fc7a81391c 100644 --- a/ipaserver/dcerpc.py +++ b/ipaserver/dcerpc.py @@ -854,8 +854,8 @@ class TrustDomainInstance(object): We try NCACN_NP before NCACN_IP_TCP and use SMB2 before SMB1 or defaults.
