This module implements only the "idmap" 4 API, and is READONLY. Mappings must be provided in advance 5 by the administrator by adding the posixAccount/posixGroup 6 classess and relative attribute/value pairs to the users and 7 groups objects in AD</p></div><div class="refsect1" lang="en"><a name="id291819"></a><h2>IDMAP OPTIONS</h2><div class="variablelist"><dl><dt><span class="term">range = low - high</span></dt><dd><p> 8 Defines the available matching uid and gid range for which the 9 backend is authoritative.

All is needed is to set default to yes. If trusted 22 domains are present id conflicts must be resolved beforehand, there is no 23 guarantee on the order confliting mappings would be resolved at this point. 24 25 This example also shows how to leave a small non conflicting range for local 26 id allocation that may be used in internal backends like BULTIN. 27 </p><pre class="programlisting"> 28 [global] 29 idmap domains = ALLDOMAINS 30 idmap config ALLDOMAINS:backend = ad 31 idmap config ALLDOMAINS:default = yes 32 idmap config ALLDOMAINS:range = 10000 - 300000000 33 34 idmap alloc backend = tdb 35 idmap alloc config:range = 5000 - 9999 36 </pre></div><div class="refsect1" lang="en"><a name="id259562"></a><h2>AUTHOR</h2><p> 37 The original Samba software and related utilities 38 were created by Andrew Tridgell.
