.Net 6 Ubuntu jammy 22.04 base image upgrade. GSSAPI NTLM error

Saravanakumar Balachandran 40

We are planning to upgrade from .Net 6 to .Net 8 version. To prepare for that upgrade we first upgraded from ubuntu 20.04 to ubuntu 22.04. We target ubuntu 22.04 version jammy tag with amd64 architecture.

This is our base image in the Docker file and the following line updates our package list.

FROM artifactory.xyz.com/dockerhub-microsoft/dotnet/aspnet:6.0-jammy-amd64 AS base

&& apt-get update && apt-get install -y --no-install-recommends curl gss-ntlmssp tzdata \

When our application tries to authenticate and open SSRS reports we get "GSSAPI operation failed with error - Unspecified GSS failure. Minor code may provide more information (Crypto routine failure)"

We were previously using focal base image in 20.04 version and was able to render SSRS reports. Did something change with gss-ntlmssp package in 22.04 version? Kindly appreciate your response on fixing this issue. Thanks!

Can you provide more context of what your setup is in Azure? What version of gss-ntlmssp is installed?

Thanks for responding. I looked at the Container file log and it installs gss-ntlmssp 0.7.0 Version. (gss-ntlmssp:amd64 (0.7.0-4build4) ). We actually host of our application in AWS. Do you need any more information?

Thanks for reaching out. I looked at the container log and it installs gss-ntlmssp:amd64 (0.7.0-4build4). So it is gss-ntlmssp 0.7.0 version. We actually run our application in AWS. Do you need any additional information?

@Saravanakumar Balachandran You might consider opening an issue on GitHub or with AWS. I am removing the Azure tags since this is not related to an Azure issue.
