Doc Text:	Previously, when a user connected to a distributed file system (DFS) share using the smbclient utility and executed the dfsgetinfo command, the smbd service handling the connection failed with a segmentation fault error. The bug has been fixed, and as a result, smbd no longer crashes when executing dfsgetinfo on a DFS share using smbclient.

Comment 3 Heinrich Mislik 2018-05-23 12:11:10 EDT

Doc Text ist not accurate. The crash happend in smbd an the server side regardless of the client. smbclient and rpcclient in samba-bug 13370 were just used to send dfs-requests to smbd.

Hello Andreas,
1. Is there any way to work around this bug?
2. If there is no work around, can we get a hotfix for the customer in support case #02118446? This issue is very critical for them.
