https://bugzilla.samba.org/show_bug.cgi?id=14713 --- Comment #32 from Ronnie Sahlberg <ronniesahlberg@xxxxxxxxx> --- Note that in vers=3.1.1 the TreeConnect calls are always signed which means that client and server must agree on what the session key is. Just like when encryption is used. Try to see what happens if you use vers=3.0 in this scenario as the TreeConnect will not be signed. It does sound like there is something wrong with the session key and client and server disagree on it. -- You are receiving this mail because: You are the QA Contact for the bug.
