krb5_db_init being used in do_as_req.c

[Anil Belur]

Hello,

We are enabling the LDAP plugin to update the attributes like
krbLastSuccessfulAuth, krbLastFailedAuth and krbLoginFailedCount.
I came across some parts of the code are which are not DAL enabled.
These parts of the code contains reference to krb5_db_init and
krb5_db_set_name API's. (do_as_req.c and loadv4.c)
The problem occurred while doing a configure with --with-kdc-kdb-update
option. 

Build details:
gcc -L../lib  -Wl,-rpath -Wl,/home/builds/krb5-1.5/bins//lib -g -Wall

do_as_req.o(.text+0xfab): In function `process_as_req':
/home/builds/krb5-1.5/src/kdc/do_as_req.c:481: undefined reference to
`krb5_db_set_name'
do_as_req.o(.text+0xfbe):/home/builds/krb5-1.5/src/kdc/do_as_req.c:483:
undefined reference to `krb5_db_init'

I was considering replacing the existing with the code with the code
below. (in do_as_req.c)

#ifdef  KRBCONF_KDC_MODIFIES_KDB
    if (update_client) {
            krb5_db_put_principal(kdc_context, &client, &c_nprincs);
            /*
             ** ptooey.  We want krb5_db_sync() or something like
that.
             **/
            krb5_db_fini(kdc_context);
            if (kdc_active_realm->realm_dbname)
+                    if ((errcode =
krb5_set_default_realm(kdc_active_realm->realm_context,
kdc_active_realm->realm_dbname))) {
+                            return errcode;
                    }

+            if((errcode =
krb5_db_open(kdc_active_realm->realm_context, db_args,
+                                           KRB5_KDB_OPEN_RW |
KRB5_KDB_SRV_TYPE_KDC)))
                    return errcode;
            /* Reset master key */
            krb5_db_set_mkey(kdc_context,
&kdc_active_realm->realm_mkey);
    }
#endif  /* KRBCONF_KDC_MODIFIES_KDB */

Let me know if this is fine.

Thanks,
