In pur environment we have changed eUPN of few users so that they eUPN and email address are matching. But after this change those users are unable to login to Linux machine which is using ad credentials to login.
Previously eUPN & iUPN where same and there was no issues. Did anyone faced this issue before. I'm not a Linux guy but our Linux team is unable to fix this issue. So if i get any input i can fwd to them to make the changes in their configuration file
