Hello everyone,

we have some SLES12 SP2 servers, which are integratet in AD domain.
For about two weeks its no possible to login with a local user by a ftp client.

vsftpd[13188]: pam_winbind(vsftpd:auth): request wbcLogonUser failed: WBC_ERR_AUTH_ERROR, PAM error: PAM_USER_UNKNOWN (10), NTSTATUS: NT_STATUS_NO_SUCH_USER, Error message was: No such user
The user exists and the passwort ist correct (really).
I'm able to login with the user by a ssh shell.

In my opinion the ftp server tries to authenticate the local user against the active directory.
But thats no correct and won't work.
