Hello, members. I followed the upgrading suggestion. Now working on Freeradius 3.2.1 (on Debian 11.5). I'm also using some personalized templates of the Eduroam/GARR consortium. Trying to setup LDAP filtering. To get an idea on how to do it, I read the tread "LDAP groups and how to filter" (https://lists.freeradius.org/pipermail/freeradius-users/2020-February/097430...) Is it still up to date? Is it a feasible solution? I'm still not understanding if this solution also requires the memberof/membership settings in the mods-available/ldap module. Does it? Now my main concern is the LDAPS binding, which is not working. Debug last rows: rlm_ldap (ldap): Opening additional connection (0), 1 of 32 pending slots used rlm_ldap (ldap): Connecting to ldaps://dc1.testuni.it:636 rlm_ldap (ldap): Bind with CN=reader-freeradius,OU=ServiceUsers,OU=ServicePeople,DC=testuni,DC=it to ldaps://dc1.testuni.it:636 failed: Can't contact LDAP server rlm_ldap (ldap): Opening connection failed (0) rlm_ldap (ldap): Removing connection pool /etc/freeradius/3.0/mods-enabled/ldap[8]: Instantiation failed for module "ldap" I tried to bind, manually, using the general command: ldapsearch -D ${identity} -w ${password} -H ${server} -b 'CN=user,${base_dn}' and it worked. In mods-available/ldap, at line 77, I read the suggestion: ldapsearch -D ${identity} -w ${password} -h ${server} -b 'CN=user,${base_dn}' which did not work (the "-h" parameter is not supported anymore?). I don't think that this is the exact command used by freeradius, so the cause is elsewhere, likely in my configuration files. What am I supposed to check? Do you need the full debug? Thanks in advance, Pietro
