BUGS: at least two in pdb_ldap.c

[Donny Davies]

  Lines 1705 and 1714 are obviously incorrect.

  I tried patching locally here by replacing "nextUserRid" with
get_attr_key2string(dominfo_attr_list, LDAP_ATTR_NEXT_USERRID)
and similarly replacing "nextGroupRid" with
get_attr_key2string(dominfo_attr_list, LDAP_ATTR_NEXT_GROUPRID)
which lets me get further with `smbpasswd -a -m foo' than i did
before, but it still doesnt work and I end up triggering:

DEBUG(0, ("NO user RID specified on account %s, and "
"finding next available NUA RID failed, "
"cannot store!\n", pdb_get_username(sampass)));

  I'm afraid I don't know how to fix this.  Please take a look.

  Thanks.
