Target Device Naming Requirements for LDAP ImplementationLogin Failure. Reason: Access cannot be granted due to Authentication Server errorsPlease verify that the SIP object was created in the Active Directory and its name exactly matches the name assigned to that SIP via the OSCAR at the console switch.The Dell Standard Schema and the Dell Extended Schema use specific object classes in the Microsoft Windows Active Directory to represent SIPs. The Microsoft standard naming conventions for these object classes prohibit the use of special characters or spaces. If you intend to use LDAP in a deployed environment where target device names in SIPs currently include spaces or special characters, you will need to rename them without spaces or special characters.Renaming a target device in a SIP should be done through the on-board web interface or OSCAR at the console switch and then resynchronized through the Remote Console Switch Software. Instructions for renaming a target device in a SIP can be found in “Deleting and Renaming” and “Assigning Device Names”. It is important to note that while OSCAR will allow you to enter spaces into the names assigned to the SIPs, Active Directory does not. You must name SIP objects according to the Microsoft Active Directory rules.
