Description

This function adds additional Slapi_Value data values to the existing values contained in an attribute. If the attribute type does not exist, it is created.

If the specified attribute exists in the entry, the function merges the value specified and returns LDAP_SUCCESS. If the attribute is not found in the entry, the function creates it with the Slapi_Value specified and returns LDAP_NO_SUCH_ATTRIBUTE.

Notice that if this function fails, it leaves the values for type within a pointer to e in an indeterminate state. The present value set may be truncated.
