6 <para>If <command moreinfo="none">samba</command> is running as an
7 active directory domain controller, it is possible to store the
8 cleartext password of accounts in a PGP/OpenGPG encrypted form.</para>
10 <para>You can specify one or more recipients by key id or user id.
11 Note that 32bit key ids are not allowed, specify at least 64bit.</para>
13 <para>The value is stored as 'Primary:SambaGPG' in the
14 <command moreinfo="none">supplementalCredentials</command> attribute.</para>
16 <para>As password changes can occur on any domain controller,
17 you should configure this on each of them. Note that this feature is currently
18 available only on Samba domain controllers.</para>
20 <para>This option is only available if <command moreinfo="none">samba</command>
21 was compiled with <command moreinfo="none">gpgme</command> support.</para>
23 <para>You may need to export the <command moreinfo="none">GNUPGHOME</command>
24 environment variable before starting <command moreinfo="none">samba</command>.
25 <emphasis>It is strongly recommended to only store the public key in this
26 location. The private key is not used for encryption and should be
27 only stored where decryption is required.</emphasis></para>
29 <para>Being able to restore the cleartext password helps, when they need to be imported
30 into other authentication systems later (see <command moreinfo="none">samba-tool user getpassword</command>)
31 or you want to keep the passwords in sync with another system, e.g. an OpenLDAP server
32 (see <command moreinfo="none">samba-tool user syncpasswords</command>).</para>
34 <para>While this option needs to be configured on all domain controllers, the
35 <command moreinfo="none">samba-tool user syncpasswords</command> command should
36 run on a single domain controller only (typically the PDC-emulator).</para>
