Unable to enable LDAP Authentication

Hi!
My configuration, which uses an ldap connection, looks like this:
#-# The group management class.

xwiki.authentication.groupclass=com.xpn.xwiki.user.impl.xwiki.XWikiGroupServiceImpl

#-# The authentication management class.
xwiki.authentication.authclass=org.xwiki.contrib.ldap.XWikiLDAPAuthServiceImpl
xwiki.authentication.ldap=1
xwiki.authentication.ldap.trylocal=1
xwiki.authentication.ldap.server=ad-ldap.int.test.org
xwiki.authentication.ldap.bind_DN=ad-username
xwiki.authentication.ldap.bind_pass=ad-pass
xwiki.authentication.ldap.base_DN=dc=tst,dc=int,dc=test,dc=org
xwiki.authentication.ldap.UID_attr=sAMAccountName
xwiki.authentication.ldap.user_group=cn=Group_user,ou=exemple1,ou=exemple2,ou=Groups,ou=test,dc=tst,dc=int,dc=test,dc=org
xwiki.authentication.ldap.fields_mapping=last_name=sn,first_name=givenName
xwiki.authentication.ldap.update_user=1

However, there is a problem: when I configure LDAP to work, the page deletion function stops working.

An error appears instead of the deletion confirmation page. I think I mentioned this earlier, I’ll look for it now.
