Hello, I'v to migrate one file server (old samba 3) to a new file samba 4, I thought I could use the parameters netbios aliases = oldsamba but it doesn't work, trying to access the share, with the old names, the credentials popup appears and the log show: gss_accept_sec_context failed with [ Miscellaneous failure (see text): Failed to find cifs/oldsamba3 at lan.corp(kvno 107) in keytab MEMORY:cifs_srv_keytab (arcfour-hmac-md5)] unfortunately I have to keep active also the old server for which I thought I could solve with the dns. any help? thnx.
For this to work Below shows a A on the old hostname, correct ? With the "netbios alias" used in samba. Setup like this : The new server.. hostname => DNS A IP => DNS PTR Netbios Alias => CNAME OLDSERVERNAME And try again. Remove the A/PTR of the old hostname also. Only a CNAME is sufficient.. Note, the new server MUST have A and PTR setup. optional, set dns proxy = yes in smb.conf Greetz, Louis> -----Oorspronkelijk bericht----- > Van: samba [mailto:samba-bounces at lists.samba.org] Namens > banda bassotti via samba > Verzonden: donderdag 26 september 2019 11:13 > Aan: samba at lists.samba.org > Onderwerp: [Samba] access to share with dns alias hostname > > Hello, I'v to migrate one file server (old samba 3) to a new > file samba 4, > I thought I could use the parameters netbios aliases = oldsamba but it > doesn't work, trying to access the share, with the old names, the > credentials popup appears and the log show: > > gss_accept_sec_context failed with [ Miscellaneous failure > (see text): > Failed to find cifs/oldsamba3 at lan.corp(kvno 107) in keytab > MEMORY:cifs_srv_keytab (arcfour-hmac-md5)] > > unfortunately I have to keep active also the old server for > which I thought > I could solve with the dns. > > any help? > > thnx. > -- > To unsubscribe from this list go to the following URL and read the > instructions: https://lists.samba.org/mailman/options/samba > >

It sounds to me that the OP has classicupgraded an NT4-style domain to an AD domain. If so, then unless he has modified the smb.conf, the old machine will still be running as a PDC. I think he needs to give us more info. Starting with the smb.conf from the new AD DC and the old PDC. Rowland> > >

If so, get them to sort it out for you, that is what you are paying for. If not, then post the smb.conf from the UCS machine and the smb.conf from the old machine. Rowland
