I have a graduation project. I try to config a captive portal on a routeur Zeroshell for my Samba AD i have a problem when i try to connect on the portal with a member of my AD , its not working , i have a ” ACCESS DENIED !!! , email@example.com not connected USER Unknown or invalid password” . When i watch the logs of captive portal and i see ” AS : kinit(v5): Cannot find KDC for requested realm while getting initial credentials^M
“AS: warning: authentification failed for the user firstname.lastname@example.org”
Does anyone have a suggestion to this problem , What should I check or configure on my samba to fix the problem?
