Schema extension errors

The following can help you troubleshoot some error messages you might encounter when extending the schema for your AWS Managed Microsoft AD directory.

Referral

Error

Add error on entry starting on line 1: Referral The server side error is: 0x202b A referral was returned from the server. The extended server error is: 0000202B: RefErr: DSID-0310082F, data 0, 1 access points \tref 1: ‘example.com’ Number of Objects Modified: 0

Troubleshooting

Ensure that all of the distinguished name fields have the correct domain name. In the example above, DC=example,dc=com should be replaced with the DistinguishedName shown by the cmdlet Get-ADDomain.

Unable to read import file

Error

Unable to read the import file. Number of Objects Modified: 0

Troubleshooting

The imported LDIF file is empty (0 bytes). Ensure the correct file was uploaded.

Syntax error

Error

There is a syntax error in the input file Failed on line 21. The last token starts with 'q'. Number of Objects Modified: 0

Troubleshooting

The text on line 21 is not formatted correctly. The first letter of the invalid text is A. Update line 21 with valid LDIF syntax. For more information about how to format the LDIF file, see Step 1: Create your LDIF file.

Attribute or value exists

Error

Add error on entry starting on line 1: Attribute Or Value Exists The server side error is: 0x2083 The specified value already exists. The extended server error is: 00002083: AtrErr: DSID-03151830, #1: \t0: 00002083: DSID-03151830, problem 1006 (ATT_OR_VALUE_EXISTS), data 0, Att 20019 (mayContain):len 4 Number of Objects Modified: 0

Troubleshooting

The schema change has already been applied.

No such attribute

Error

Add error on entry starting on line 1: No Such Attribute The server side error is: 0x2085 The attribute value cannot be removed because it is not present on the object. The extended server error is: 00002085: AtrErr: DSID-03152367, #1: \t0: 00002085: DSID-03152367, problem 1001 (NO_ATTRIBUTE_OR_VAL), data 0, Att 20019 (mayContain):len 4 Number of Objects Modified: 0

Troubleshooting

The LDIF file is trying to remove an attribute from a class, but that attribute is currently not attached to the class. Schema change was probably already applied.

Error

Add error on entry starting on line 41: No Such Attribute 0x57 The parameter is incorrect. The extended server error is: 0x208d Directory object not found. The extended server error is: "00000057: LdapErr: DSID-0C090D8A, comment: Error in attribute conversion operation, data 0, v2580" Number of Objects Modified: 0

Troubleshooting

The attribute listed on line 41 is incorrect. Double-check the spelling.

No such object

Error

Add error on entry starting on line 1: No Such Object The server side error is: 0x208d Directory object not found. The extended server error is: 0000208D: NameErr: DSID-03100238, problem 2001 (NO_OBJECT), data 0, best match of: ’CN=Schema,CN=Configuration,DC=example,DC=com’ Number of Objects Modified: 0
