I don't have any additional information on the meaning of the DSID error code but this error text is normally part of the extended error message returned by the LDAP client. With the MS LDAP client there is normally additional text after the DSID error text that provides more information, as shown below:
Server Error: 0000216B: AtrErr: DSID-03140561, #1: 0: 0000216B: DSID-03140561, problem 1004 (WRONG_MATCH_OPER), data 0, Att 90515 (tokenGroups) , Ext Error: (8555) A Filter was passed that uses constructed attributes.
If you are using the MS LDAP client, call the LdapGetLastError function which will return the short error code, which is searchable. For the above example the short error code is:
Error: (0x12) There was an inappropriate matching
I hope that helps.
