I get regularly the following warning in my event log: Windows(R) Lightweight Directory Access Protocol (LDAP) failed a request to connect to Active Directory Domain Services(R) for Windows user <NT-AUTORITÄT\SYSTEM> Without the corresponding UNIX identity of the Windows user the user cannot access Network File System (NFS) shared resources. Verify that the Windows user is in Active Directory Domain Services and has access permissions. ... but I can't find a solution. Any hints for me ?
