The Directory Server implementation of the DSMLv2 specification has the following restrictions:
DSMLv2 defines two normative bindings: a SOAP request/response binding and a file binding that serves as the DSMLv2 analog of LDIF. Directory Server supports the SOAP request/response binding.
Directory Server supports the DSML modDNRequest and modDNResponse operations.
Directory Server does not support the abandonRequest operation, because this operation is of no use over HTTP.
Some DSML clients incorrectly send an equality match with value * when a presence match is intended. Directory Server will return zero results from these badly formatted queries. You can detect these incorrect clients by searching for the characters =\2a in the access log.
