During validation stage

The Server API does some minor error checking on the arguments passed to it. Most of the error checking must be done by the OSA. The Server API will generate errors for:

• specifying an attribute multiple times.

• specifying an attribute which is already implicitly specified via a group attribute.

• passing attributes to the delete operation.

• passing attributes with values to the get and replaceWithDefault operations. (SCO_OSA_ERR_INVALID_ATTRIBUTE_VALUE)

• passing attributes without values to the replace, add, remove and create operations. (SCO_OSA_ERR_INVALID_ATTRIBUTE_VALUE)

• specifying an unsupported operation. (SCO_OSA_ERR_UNRECOGNIZED_OPERATION)

• specifying an illegal attribute. (SCO_OSA_ERR_NO_SUCH_ATTRIBUTE)

• specifying an illegal object class. (SCO_OSA_ERR_NO_SUCH_OBJECT_CLASS)

• containing a garbled command. (SCO_OSA_ERR_MISTYPED_ARGUMENT)

• specifying an illegal filter. (SCO_OSA_ERR_INVALID_FILTER)

• Assigning set values to a single valued attribute. (SCO_OSA_ERR_INVALID_ATTRIBUTE_VALUE)

• specifying an attribute without a value for the set, replace, add, create or remove operation. (SCO_OSA_ERR_MISSING_ATTRIBUTE_VALUE)
