Could not resolve 'privacyidea:serverconfig'

Hi everybody!
I am trying to connect privacyIdea with simplesamlphp via simplesamlphp-module-privacyidea
I installed it in a virtual machine together: simplesamlphp + privacyidea with the ethernet adaptor in bridged mode ( In this way, I have a functional IP ).
Previously, simplesamlphp is working alone, but at the moment that I configured the plugin it crashes.
I am setting it via the saml20-sp-remote.php, via authproc:

'authproc' => array(
    20 => array(
        'class'             => 'privacyidea:serverconfig',
        'privacyideaserver' => 'https://IP.IS.HERE',   
        'realm'             => 'prueba',
        'uidKey'        => array('uid', 'userName', 'uName'),
        'sslverifyhost'     => false,
        'sslverifypeer'     => false,
        'serviceAccount'    => 'root',
        'servicePass'       => 'root',
   ),
 25 => array(
        'class'             => 'privacyidea:privacyidea',
),
),
);

I enrolled a HOTP token to my user in privacyidea admin Web-UI, and I am using a LDAP as userresolver.
LDAP is working well in tests and getting information about my user.

At the moment that I try to autenticate versus simplesaml, I get this error:

SimpleSAML\Error\Error: UNHANDLEDEXCEPTION

I installed the plugin with composer.
php composer.phar require privacyidea/simplesamlphp-module-privacyidea:v1.6

I am using last version of privacyIdea and PHP 7.2.24-0ubuntu0.18.04.7 in a ubuntu 18.04.

Thanks

I removed simplesamlphp-module-privacyidea via composer and reinstalled without setting version.
It has installed 1.8 version of this plugin.

I got the second factor asking for password. (I think that I need to put my ldap password + otp from google autenticator ).

I get this message:

SimpleSAML\Error\BadRequest: BADREQUEST(’%REASON%’ => ‘privacyIDEA: Valid JSON response, but some internal error occured in PI server’)

The illegal offset type… its so strange… any idea??

Thanks

After a lot off changes, finally I get working!!
You need to set:
‘uidKey’ => ‘sAMAccountName’,
In the authproc, it resolves the illegal offset of the previous message. The problem is that simplesaml is sending the user with that name… and PrivacyIdea don’t know that if you don’t say especifically.
Now, enroll a new token hotp or totp to the user, try to autenticate… and it works.

Now I am working with the auto enrollment and with other types of enrollment.

Which user is used in serviceAccount??
root from local machine?
a user from resolvers ??
I have a ldap server with all the users and a local machine with their local users.
I have a user in ldap for queries, this one is for this purpose?

The user User(login=‘root’, realm=‘prueba’, resolver=’’) exists in NO resolver.

It seems that you need to use the ldap user to query ldap server:

[2020-11-18 14:03:22,138][16533][140128627881728][INFO][privacyidea.lib.user:233] user ‘queryldap’ found in resolver ‘ldapServer’
[2020-11-18 14:03:22,142][16533][140128627881728][INFO][privacyidea.lib.user:234] userid resolved to ‘UID’

I’m not sure about tokenEnrollment, that you can enable in authoproc.
Is token created at the time? Must token be created before but without association? any policy to set??

My prodecure is:
No token created in authproc, I set tokenEnrollment enable with hotp.
When I try the 2FA, I get a new token created for the ldap query user… but no one for the user that I’m trying to autheticate.
Any idea?
When do I set the pin for a token?

Thanks in advance.
