and that extension is not compatible with TYPO3 for quite some time
now.

-.. question
-
-**I am currently using another LDAP extension to authenticate my users, namely** :ter:`eu_ldap`. **Does this extension
-at least provide the same feature set?**
-
-.. answer
-
-*Yes. And in order to ease the migration, this extension is able to migrate your legacy eu_ldap configuration records
-to be compatible with ig_ldap_sso_auth using the "UPDATE!" script in Extension Manager (EM). You should first configure
-global options for ig_ldap_sso_auth in EM and only then migrate your legacy eu_ldap configuration records. This will
-ensure possible configuration issues to be detected.*
-
-.. hint::
-	The migration wizard does not require extension eu_ldap to be **loaded** but only expects the corresponding
-	database table to be present.
