This module implements only the "idmap" 24 API, and is READONLY. Mappings must be provided in advance 25 by the administrator by adding the posixAccount/posixGroup 26 classes and relative attribute/value pairs to the user and 27 group objects in the AD.</para> 28</refsynopsisdiv> 29 30<refsect1> 31 <title>IDMAP OPTIONS</title> 32 33 <variablelist> 34 <varlistentry> 35 <term>range = low - high</term> 36 <listitem><para> 37 Defines the available matching UID and GID range for which the 38 backend is authoritative. Note that the range acts as a filter. 39 If specified any UID or GID stored in AD that fall outside the 40 range is ignored and the corresponding map is discarded. 41 It is intended as a way to avoid accidental UID/GID overlaps 42 between local and remotely defined IDs. 43 </para></listitem> 44 </varlistentry> 45 <varlistentry> 46 <term>schema_mode = <rfc2307 | sfu ></term> 47 <listitem><para> 48 Defines the schema that idmap_ad should use when querying 49 Active Directory regarding user and group information. 50 This can be either the RFC2307 schema support included 51 in Windows 2003 R2 or the Service for Unix (SFU) schema. 52 </para></listitem> 53 </varlistentry> 54 </variablelist> 55</refsect1> 56 57<refsect1> 58 <title>EXAMPLES</title> 59 <para> 60 The following example shows how to retrieve idmappings from our principal and 61 trusted AD domains. If trusted domains are present id conflicts must be 62 resolved beforehand, there is no 63 guarantee on the order conflicting mappings would be resolved at this point. 64 65 This example also shows how to leave a small non conflicting range for local 66 id allocation that may be used in internal backends like BUILTIN. 67 </para> 68 69 <programlisting> 70 [global] 71 idmap backend = tdb 72 idmap uid = 1000000-1999999 73 idmap gid = 1000000-1999999 74 75 idmap config CORP : backend = ad 76 idmap config CORP : range = 1000-999999 77 </programlisting> 78</refsect1> 79 80<refsect1> 81 <title>AUTHOR</title> 82 83 <para> 84 The original Samba software and related utilities 85 were created by Andrew Tridgell.
