https://bugzilla.samba.org/show_bug.cgi?id=14713 --- Comment #21 from Steve French <sfrench@xxxxxxxxx> --- Key next steps: 1) seeing if it is possible to decrypt the wireshark trace (see link provided earlier for instructions) although this may require rebuilding the cifs.ko to dump keys (does Solaris have a way to view encrypted traces taken on the server side?) 2) looking in more detail at the server. It doesn't indicate why it was rejected: ./../common/fs/smbsrv/smb2_dispatch.c:smb2_dispatch_message:134:Decryption failure (71)! May 25 19:44:21 nonsuch smbcmn: [ID 997540 kern.warning] WARNING: ../../common/fs/smbsrv/smb2_dispatch.c:smb2_dispatch_message:134:Decryption failure (72)! Do you have any contacts with Solaris support to see if they can see if they can provide more information? My guess is that they don't like the format or the flags of something specified in the tree connect (since this works to every other server type) - but they may also have some subtle rounding error with decryption on their server side. Googling for the error I do see one other report of similar sounding problem to Solaris so it has been around a long time (see https://bugs.centos.org/view.php?id=16531) -- You are receiving this mail because: You are the QA Contact for the bug.
