I have a problem and hope someone can help me. I have SQL Server as docker container. I want our developers able to login in SSMS (SQL Server Management Studio) using their Active Directory users. I followed this procedures which was Microsoft Doc page but it didn't work. The log file in container shows about error:

Login failed. The login is from an untrusted domain and cannot be used with Integrated authentication. [CLIENT:]

Error: 17806, Severity: 20, State: 14.
SSPI handshake failed with error code 0x80090304, state 14 while establishing a connection with integrated security; the connection has been closed.
Reason: AcceptSecurityContext failed. The operating system error code indicates the cause of failure. The Local Security Authority cannot be contacted [CLIENT:]

My container run successfully and I can connect to it using sa user but, I can't login using Windows Authentication. This is my docker run command:

# docker run -itd -e "ACCEPT_EULA=Y" -e "SA_PASSWORD=<pass>" -p 1433:1433 --name msdb \
--user root \
-v /root/mssql:/var/opt/mssql/ \
-v /root/mssql/krb5.conf:/etc/krb5.conf \
--dns-search <full domain> \
--dns \
--add-host <dc.mydomain>: \
--add-host <mydomain>: \
--add-host <my domain.com>: mcr.microsoft.com/mssql/server

Also, I checked this checklists but the problem didn't resolve and I got the same error again.

I hope some one can help me how can I resolve it.


  • Is your client machine running SSMS joined to the domain? If not then are you using Runas to start SSMS so that it has domain context? – Martin Cairney Jan 31 at 22:21
  • Does the SQL error log have any entries regarding kerberos and the SPN? Can you post the lines from the log? – Martin Cairney Feb 1 at 9:46
  • I'd also try the debugging mentioned at bobsql.com/… – Martin Cairney Feb 1 at 9:49

@Martin Cairry, Yes, client is windows 10 and its joined the domain, ssms verion is 18.5. all users have domain admin privilege. Also when I login to ssms with sa user, I can add my domain user in login section but it can't login using windows authentication.
