ERROR_DS_INVALID_ATTRIBUTE_SYNTAX
ERROR_DS_INVALID_ATTRIBUTE_SYNTAX (0x0000200B) is an Active Directory Domain Services LDAP result. The attribute value does not match the syntax defined for that attribute in the Active Directory schema.
What to check
- Check the attribute syntax and whether the client sent the correct value type, encoding, and format.
- For a distinguished name value, validate every RDN component and escaping rule.
- Do not replace a value with a guessed format; inspect the schema definition and a known-good object first.
