Hello everybody I am using limesurvey3.25.1+201124.zip and I am keep getting "Can't contact LDAP server" after enabling and configuring the LDAP plugin.

I checked with tcpdump to the host and I can not get any traffic when I try to login...

tcpdump -i enp1s0 host 192.168.40.20

ldap://192.168.40.20 (tried fqdn as well)
389
LDAPv3 (tried LDAPv2)
Search and bind
uid
cn=users,cn=accounts,dc=organization,dc=lan
(objectclass=*) tried (&(objectclass=*)(uid=$username))
uid=externalldapadmin,cn=sysaccounts,cn=etc,dc=organization,dc=lan
<passwd>
mail
displayName
Check to make default authentication method (checked)
Automatically create user if it exists in LDAP server (checked)
Allow initial user to login via LDAP (checked)

I am normally pretty good with LDAP configs, how can I debug this? How can I get some php debugging going on to see any logs? /var/www/html/limesurvey/application/core/plugins/AuthLDAP/AuthLDAP.php ??

I have not changed anything in /var/www/html/limesurvey/application/config/ldap.php should I? I only used the GUI for the config...

Thank you in advance!

I had an selinux issue that was blocking the ldap connection! I solved it and the auth is working now!

Maybe you can create a new part here : www.limesurvey.org/manual/Authentication...erver_authentication
