Background:
I have a samba cifs server. It is not joined to a domain, but has a keytab for an MIT kerberosV realm.
Kerberized mounts (e.g. mount -t cifs //cifs.example.com/groups /mnt/cifs -o sec=krb5i) work from Linux clients.
Kerberized mounts from AD joined windows machines (joined to a domain configured with a trust to the Kerberos Realm). Password based mounts don't work for Linux clients (not a big deal).
Password based mounts for non AD joined Windows clients kind of work. Using explorer to go to \\cifs.example.com\groups will not work, and no password prompt will appear. However, if \\cifs.example.com\groups is mounted as a letter drive, the dialog will not complete, but the drive mapping will be established and work, and the dialog box can be canceled at this point while retaining the mount.
Question:
- How can a make the UNC path prompt for a password on non AD joined Windows machines?
