User Authentication with IMAP, SMB, and FTP¶
You may configure additional user backends
in Nextcloud’s configuration config/config.php using the following
syntax:
<?php
"user_backends" => array (
0 => array (
"class" => ...,
"arguments" => array (
0 => ...
),
),
),
Note
A non-blocking or correctly configured SELinux setup is needed for these backends to work. Please refer to the SELinux Configuration.
Currently the “External user support” (user_external) app, which you need to enable first (See Installing and Managing Apps) provides the following user backends:
IMAP¶
Provides authentication against IMAP servers
- Class: OC_User_IMAP
- Arguments: a mailbox string as defined in the PHP documentation
- Dependency: php-imap (See Installation on Linux)
- Example:
<?php
"user_backends" => array (
0 => array (
"class" => "OC_User_IMAP",
"arguments" => array (
0 => '{imap.gmail.com:993/imap/ssl}'
),
),
),
SMB¶
Provides authentication against Samba servers
- Class: OC_User_SMB
- Arguments: the samba server to authenticate against
- Dependency: PHP smbclient module or smbclient (see SMB/CIFS)
- Example:
<?php
"user_backends" => array (
0 => array (
"class" => "OC_User_SMB",
"arguments" => array (
0 => 'localhost'
),
),
),
FTP¶
Provides authentication against FTP servers
- Class: OC_User_FTP
- Arguments: the FTP server to authenticate against
- Dependency: php-ftp (See Installation on Linux)
- Example:
<?php
"user_backends" => array (
0 => array (
"class" => "OC_User_FTP",
"arguments" => array (
0 => 'localhost'
),
),
),
