Incomplete import of AD-Attributes via LDAP

Fresh install of Dolibarr 17.0.1 on Ubuntu 22.04LTS, Apache/2.4.52 (Ubuntu), PHP 8.1.2-1ubuntu2, MariaDB 5.5.5-10.6.12-MariaDB-0ubuntu0.22.04.1
LDAP connection into our AD (2016) works. Our primary LDAP-Key is samaccountname

Our problem is that when importing users from our AD, only some attributes are imported (like sn, givenName, mobile and mail are imported correctly), others like company, streetAddress, postalCode, I and title are not imported, although they are mapped in Dolibarr to the exact correct attribute-names as in our AD.

Does somebody have similar issues or solutions for this problem?

Merci beaucoup!
