Sun Directory Server Enterprise Edition 7.0 Developer's Guide

Verifying Schema Compliance for an Entry

This section demonstrates how to check that an entry is valid with respect to the directory schema known to Directory Server. Verify schema compliance for an entry with slapi_entry_check(). The two arguments of the function are a pointer to a parameter block and a pointer to the entry, as shown in the following example.

Example 4–7 Checking Schema Compliance (entries.c)

#include "slapi-plugin.h"

    Slapi_Entry * entry = NULL;        /* Original entry          */
    Slapi_Entry * ecopy = NULL;        /* Copy entry              */

    entry = slapi_entry_alloc();

    /* Add code to fill the entry, setting the DN and attributes. */

    ecopy = slapi_entry_dup(entry);
    slapi_entry_set_dn(ecopy, slapi_ch_strdup("dc=example,dc=org"));
    slapi_entry_add_string(ecopy, "description", "A copy of the orig.");
    /* Does the resulting copy comply with the schema?            */
    if (slapi_entry_schema_check(NULL, ecopy) == 0) {
        /* Resulting entry does comply. */ ;
    } else {
        /* Resulting entry does not comply. */ ;


    return (0);

Notice that the parameter block pointer argument is NULL. Leave the parameter block pointer argument NULL in most cases. When the plug-in is used in a replicated environment, you can use the argument to prevent schema compliance verification for replicated operations.
