Event Details
| Product: | Windows Operating System |
| ID: | 4011 |
| Source: | NfsService |
| Version: | 6.1 |
| Symbolic Name: | ERR_NFS_LDAP_NOT_UNIQUE_UID |
| Message: | Active Directory Domain Services(R) contains multiple users which match attribute <%1>. Only one Windows(R) user should be assoicated with each UNIX UID. With multiple Windows users associated with one UNIX UID, Server for NFS cannot determine which Windows user is requesting access to files. No Windows users associated with the same UNIX UID will be able to access files through Server for NFS. Try removing the duplicate UNIX UID entries. |
Resolve
