AuthUnknown

Indicates that a bind method was called with an unknown authentication method. AUTH_UNKNOWN = 86
Busy

Indicates that the Ldap server is too busy to process the client request at this time, but if the client waits and resubmits the request, the server may be able to process it then. BUSY = 51

InappropriateAuthentication

Indicates that during a bind operation, the client is attempting to use an authentication method that the client cannot use correctly. For example, either of the following cause this error:

  • The client returns simple credentials when strong credentials are required.
  • The client returns a DN and a password for a simple bind when the entry does not have a password defined.
INAPPROPRIATE_AUTHENTICATION = 48

LdapPartialResults

Returned by some Ldap servers to Ldapv2 clients to indicate that a referral has been returned in the error string. Ldap_PARTIAL_RESULTS = 9
LdapTimeout

Indicates that the time limit of the Ldap client was exceeded while waiting for a result. Ldap_TIMEOUT = 85
LocalError

Indicates that the Ldap client has an error. This is usually a failed dynamic memory allocation error. LOCAL_ERROR = 82
LoopDetect

Indicates that the client discovered an alias or referral loop, and is thus unable to complete this request. LOOP_DETECT = 54
MoreResultsToReturn

Indicates that more results are chained in the result message. MORE_RESULTS_TO_RETURN = 95
NamingViolation

Indicates that the add or modify DN operation violates the schema's structure rules. For example,

  • The request places the entry subordinate to an alias.
  • The request places the entry subordinate to a container that is forbidden by the containment rules.
  • The RDN for the entry uses a forbidden attribute type.
NAMING_VIOLATION = 64
NoMemory

Indicates that a dynamic memory allocation method failed when calling an Ldap method. NO_MEMORY = 90
NoResultsReturned

Indicates that the Ldap server sent no results. NO_RESULTS_RETURNED = 94
NoSuchAttribute

Indicates that the attribute specified in the modify or compare operation does not exist in the entry. NO_SUCH_ATTRIBUTE = 16
NoSuchObject

Indicates the target object cannot be found. This code is not returned on the following operations:

  • Search operations that find the search base but cannot find any entries that match the search filter.
  • Bind operations.
NO_SUCH_OBJECT = 32
NotAllowedOnNonleaf

Indicates that the requested operation is permitted only on leaf entries. For example, the following types of requests return this error:

  • The client requests a delete operation on a parent entry.
  • The client request a modify DN operation on a parent entry.
NOT_ALLOWED_ON_NONLEAF = 66
NotAllowedOnRdn

Indicates that the modify operation attempted to remove an attribute value that forms the entry's relative distinguished name. NOT_ALLOWED_ON_RDN = 67
ObjectClassModsProhibited

Indicates that the modify operation attempted to modify the structure rules of an object class. OBJECT_CLASS_MODS_PROHIBITED = 69
ObjectClassViolation

Indicates that the add, modify, or modify DN operation violates the object class rules for the entry. For example, the following types of request return this error:

  • The add or modify operation tries to add an entry without a value for a required attribute.
  • The add or modify operation tries to add an entry with a value for an attribute which the class definition does not contain.
  • The modify operation tries to remove a required attribute without removing the auxiliary class that defines the attribute as required.
OBJECT_CLASS_VIOLATION = 65
OperationsError

Indicates an internal error. The server is unable to respond with a more specific error and is also unable to properly respond to a request. It does not indicate that the client has sent an erroneous message. OPERATIONS_ERROR = 1
Other

Indicates an unknown error condition. OTHER = 80
ProtocolError

Indicates that the server has received an invalid or malformed request from the client. PROTOCOL_ERROR = 2
Referral

Does not indicate an error condition. In Ldapv3, indicates that the server does not hold the target entry of the request, but that the servers in the referral field may. REFERRAL = 10
ReferralLimitExceeded

Indicates that the referral exceeds the hop limit. The default hop limit is ten. The hop limit determines how many servers the client can hop through to retrieve data. For example, suppose the following conditions:

  • Suppose the hop limit is two.
  • If the referral is to server D which can be contacted only through server B (1 hop) which contacts server C (2 hops) which contacts server D (3 hops).
With these conditions, the hop limit is exceeded and the Ldap libraries set this code. REFERRAL_LIMIT_EXCEEDED = 97
SaslBindInProgress

Does not indicate an error condition, but indicates that the server is ready for the next step in the process. The client must send the server the same SASL mechanism to continue the process. SASL_BIND_IN_PROGRESS = 14
ServerDown

Indicates that the Ldap libraries cannot establish an initial connection with the Ldap server. Either the Ldap server is down or the specified host name or port number is incorrect. SERVER_DOWN = 81
SizeLimitExceeded

Indicates that in a search operation, the size limit specified by the client or the server has been exceeded. Incomplete results are returned. SIZE_LIMIT_EXCEEDED = 4
SslHandshakeFailed

Indicates that SSL Handshake could not succeed. SSL_HANDSHAKE_FAILED = 113
SslProviderNotFound

Indicates that SSL Provider could not be found. SSL_PROVIDER_NOT_FOUND = 114
StrongAuthRequired

Indicates a problem with the level of authentication. One of the following has occurred:

  • In bind requests, the Ldap server accepts only strong authentication.
  • In a client request, the client requested an operation such as delete that requires strong authentication.
  • In an unsolicited notice of disconnection, the Ldap server discovers the security protecting the communication between the client and server has unexpectedly failed or been compromised.
STRONG_AUTH_REQUIRED = 8
Success

Indicates the requested client operation completed successfully. SUCCESS = 0
TimeLimitExceeded

Indicates that the operation's time limit specified by either the client or the server has been exceeded. On search operations, incomplete results are returned. TIME_LIMIT_EXCEEDED = 3
TlsNotSupported

Indicates that TLS is not supported on the server. TLS_NOT_SUPPORTED = 112
Unavailable

Indicates that the Ldap server cannot process the client's bind request, usually because it is shutting down. UNAVAILABLE = 52
UnavailableCriticalExtension

Indicates that the Ldap server was unable to satisfy a request because one or more critical extensions were not available. Either the server does not support the control or the control is not appropriate for the operation type. UNAVAILABLE_CRITICAL_EXTENSION = 12
UndefinedAttributeType

Indicates that the attribute specified in the modify or add operation does not exist in the Ldap server's schema. UNDEFINED_ATTRIBUTE_TYPE = 17
UnwillingToPerform

Indicates that the Ldap server cannot process the request because of server-defined restrictions. This error is returned for the following reasons:

  • The add entry request violates the server's structure rules.
  • The modify attribute request specifies attributes that users cannot modify.
UNWILLING_TO_PERFORM = 53
UserCancelled

Indicates that the user cancelled the Ldap operation. USER_CANCELLED = 88
