| | 0x00 | LDAP_CONNECTION SUCCESS | The operation completed successfully. |
| 1 | 0x01 | LDAP_OPERATIONS_ERROR | Invalid syntax for ACI or schema, or inappropriate control for the operation. |
| 2 | 0x02 | LDAP_PROTOCOL_ERROR | Invalid filter expression on search, or DN on add, modify, or delete. |
| 3 | 0x03 | LDAP_TIME_LIMIT_EXCEEDED | Either the server's or the client's specified search time limit was exceeded. |
| 4 | 0x04 | LDAP_SIZE_LIMIT_EXCEEDED | Either the server's or the client's specified limit on number of search results was exceeded. |
| 5 | 0x05 | LDAP_COMPARE_FALSE | A compare operation returns mismatch. |
| 6 | 0x06 | LDAP_COMPARE_TRUE | A compare operation returns match. |
| 7 | 0x07 | LDAP_STRONG_AUTH_METHOD_NOT_SUPPORTED | The server does not support the requested authentication method. |
| 8 | 0x08 | LDAP_STRONG_AUTH_REQUIRED | The server requires an authentication method stronger than unencrypted user name and password. |
| 9 | 0x09 | LDAP_PARTIAL_RESULTS | The client has bound with LDAP v2, or the server supports only LDAP v2, and the base DN specified by the client is not among the naming contexts of the server. |
| 10 | 0x0a | LDAP_REFERRAL | The server is configured to return a referral or search reference when an operation is directed toward this DN. This is an LDAP v3 error ONLY. |
| 11 | 0x0b | LDAP_ADMIN_LIMIT_EXCEEDED | To satisfy the search request, the server would need to process too many entries; the search may need to be narrowed, or the server's lookthrough limit raised. |
| 12 | 0x0c | LDAP_UNAVAILABLE_CRITICAL_EXTENSION | A control was provided with request; the control was tagged as critical, but the server doesn't support it. |
| 13 | 0x0d | LDAP_CONFIDENTIALITY_REQUIRED | This error code is new in LDAPv3. This error code may be returned if the session is not protected by a protocol which provides session confidentiality. For example, if the client did not establish a TLS connection using a cipher suite which provides confidentiality of the session before sending any other requests , and the server requires session confidentiality then the server may reject that request with a result code of confidentialityRequired . |
| 14 | 0x0e | LDAP_SASL_BIND_IN_PROGRESS | SASL authentication is being negotiated between the client and the server. |
| 16 | 0x10 | LDAP_NO_SUCH_ATTRIBUTE | An attribute to be modified or deleted was not present in the entry. |
| 17 | 0x11 | LDAP_UNDEFINED_ATTRIBUTE_TYPE | Applicable operations: Modify, Add. This error may be returned if the specified attribute is unrecognized by the server, since it is not present in the server's defined schema. If the server doesn't recognize an attribute specified in a search request as the attribute to be returned, the server should not return an error in this case - it should just return values for the requested attributes it does recognize. Note that this result code applies only to the Add and Modify operations |
| 18 | 0x12 | LDAP_INAPPROPRIATE_MATCHING | The value specified doesn't adhere to the syntax definition for that attribute. |
| 19 | 0x13 | LDAP_CONSTRAINT_VIOLATION | Invalid attribute for this entry, or new password does not meet password policy requirements |
| 20 | 0x14 | LDAP_ATTRIBUTE_OR_VALUE_EXISTS | Attempt to add an identical attribute value to an existing one. |
| 21 | 0x15 | LDAP_INVALID_ATTRIBUTE_SYNTAX | |
| 32 | 0x20 | LDAP_NO_SUCH_OBJECT | Attempt to bind with a nonexistent DN, to search with a nonexistent base DN, or to modify or delete a nonexistent DN. |
| 33 | 0x21 | LDAP_ALIAS_PROBLEM | Applicable operations: Search. An alias has been dereferenced which names no object. |
| 34 | 0x22 | LDAP_INVALID_DN_SYNTAX | Invalid DN or RDN specified on adding an entry or modifying an RDN. |
| 35 | 0x23 | LDAP_IS_LEAF | |
| 36 | 0x24 | LDAP_ALIAS_DEREFERENCING_PROBLEM | Applicable operations: Search. An alias was encountered in a situation where it was not allowed or where access was denied . For example, if the client does not have read permission for the aliasedObjectName attribute and its value, then the error aliasDereferencing Problem should be returned. |
| 48 | 0x30 | LDAP_INAPPROPRIATE_AUTHENTICATION | Applicable operations: Bind. This error should be returned by the server when the client has tried to use a method of authentication that is inappropriate. |
| 49 | 0x31 | LDAP_INVALID_CREDENTIALS | Invalid password or other credentials supplied on bind. |
| 50 | 0x32 | LDAP_INSUFFICIENT_ACCESS_RIGHTS | Give the user the proper privileges. Check the ACL rules to make sure they are correct. |
| 51 | 0x33 | LDAP_BUSY | Applicable operations: All. This error code may be returned if the server is unable to process the client's request at this time. This implies that if the client retries the request shortly, the server will be able to process it then. |
| 52 | 0x34 | LDAP_UNAVAILABLE | Returned by SDK if server is not accessible. |
| 53 | 0x35 | LDAP_UNWILLING_TO_PERFORM | User not allowed to change password, password expired , operation not implemented ( moddn ), attempt to modify read-only attribute, attempt to delete all schema elements, attempt to delete an object class that has derived object classes, attempt to delete a read-only schema element, the database is read-only, no back end (database) is available for the operation, or other uncategorized error. |
| 54 | 0x36 | LDAP_LOOP_DETECT | Applicable operations: All. This error may be returned by the server if it detects an alias or referral loop and is unable to satisfy the client's request. |
| 64 | 0x40 | LDAP_NAMING_VIOLATION | Applicable operations: Add, ModifyDN . The attempted addition or modification would violate the structure rules of the DIT as defined in the directory schema and X.501. That is, it would place an entry as the subordinate of an alias entry, or in a region of the DIT not permitted to a member of its object class, or would define an RDN for an entry to include a forbidden attribute type. |
| 65 | 0x41 | LDAP_OBJECT_CLASS_VIOLATION | Invalid attribute specified for modify operation on an entry. Update the schema. |
| 66 | 0x42 | LDAP_NOT_ALLOWED_ON_NONLEAF | Attempt to delete an entry that has child nodes. |
| 67 | 0x43 | LDAP_NOT_ALLOWED_ON_RDN | Applicable operations: Delete, ModifyDN . Attempt to modify the value of the attribute which is the RDN of the entry. |
| 68 | 0x44 | LDAP_ENTRY_ALREADY_EXISTS | No need to update the directory server, since it already has this value/entry . |
| 69 | 0x45 | LDAP_OBJECT_CLASS_MODS_PROHIBITED | Applicable operations: Modify. An operation attempted to modify an object class that should not be modified, for example, the structural object class of an entry. |
| 70 | 0x46 | LDAP_RESULTS_TOO_LARGE | |
| 71 | 0x47 | LDAP_AFFECTS_MULTIPLE_DSAS | X.500 restricts the ModifyDN operation to only affect entries that are contained within a single server. If the LDAP server is mapped onto DAP, this restriction will apply and this result code will be returned if this error occurred. |
