Resolution:
In case of failure in Target application invocation the directory server returns appropriate message corresponding to the error code.
The adapter propagates the same message to the logs.

Only the error codes are defined in the RFC 2251 the error messages are not. Hence each directory server may have a slightly different error message for the same error code mentioned in the RFC 2251.

In case of Sun One Directory Server, the error message for a particular error code defined in RFC 2251 is defined as given in the document at below link-

http://docs.sun.com/source/816-6699-10/logfiles.html#14821

Error messages returned by IBM Tivoli Directory server for corresponding error codes in the RFC 2251 can be found at-

http://publib.boulder.ibm.com/infocenter/tivihelp/v2r1/index.jsp?topic=/com.ibm.IBMDS.doc/admin_gd32.htm

For example the error message for code 71 in the RFC 2251(affectsMultipleDSAs) is "Affects multiple servers" in case of Sun One Directory server and the error message corresponding to the error code 71 affectsMultipleDSAs incase of IBM Tivoli Directory server is “Affects multiple DSAs”. The error messages for other error codes can be found in the docs in the link mentioned above.

Why does the target application invocation errorMessage shown in the TIBCO Adapter (TM) for LDAP logs not perfectly match with the one appearing in the LDAP RFC 2251?
