Community Support for OpenDocMan (Deprecated)

(03-26-2015, 11:21 AM)Did anyone end up testing this out? HyTronix Wrote: [ -> ]Hi All,


I posted to the devs mailing list, but then looking through the archives it looks like it's been dead a while.

Anyway, I wrote "users from LDAP" support.  It works fine here, but obviously I'd like to get someone else to test it.

Here's what I posted to the devs list:

Hi Devs,

I just wrote in support for getting user accounts from LDAP.  Basically, if this option is enabled, it will check LDAP for the user who is being logged in.  If the username and password match, it'll then check the opendocman database to see if the user already exists there.  If it does, it synchronizes the password field with the LDAP password.  If not, it adds a new user with defaults.  All of this is against version 1.3.2.

To test this out, you need the following in config.php:

-----8<-----
$GLOBALS['CONFIG']['ldap_enable'] = TRUE;
$GLOBALS['CONFIG']['ldap_host'] = 'my.ldaphost.com';
$GLOBALS['CONFIG']['ldap_port'] = '389';

$GLOBALS['CONFIG']['base_dn'] = "ou=People,dc=mydomain,dc=com";
$GLOBALS['CONFIG']['searchfilter'] = "(&(uid=%uid))";
$GLOBALS['CONFIG']['bind_dn'] = "cn=Manager,dc=mydomain,dc=com";
$GLOBALS['CONFIG']['bind_pw'] = "managers_password";
-----8<-----

...and then patch index.php with this patch:
