LDAPS "Cannot bind to LDAP Server" - Zabbix 4.2.5

[gr3g.f0x]

I have been struggling to get LDAPS to work.

I was able to successfully bind to the LDAPS server using ldapsearch on the Zabbix host via command line.

When I put those same settings into Zabbit, I continue to get "Cannot bind to LDAP server".

I have tried using both an FQDN for the LDAP host and IP Address.

Here are my settings in Zabbix:
LDAP Host: ldaps://IP & ldaps://FQDN
Port: 636
BaseDN: dc=example,dc=com
Search attribute: sAMAccountName
Bind DN: CN=user,OU=Service,OU=Accounts,OU=example,DC=examp le,DC=com
Case Sensitive is off.
Bind password: LDAP account password

I'm banging my head here, I cannot figure out why this isn't working.

Is there a known issue with the web interface? I can't get past that it works from cli but not from Zabbix!

Same issue here with version 4.2.6

I did some debugging now and found the issue! The problem was that, when adding the "search attribute" to the form, by mistake I have added a trailing blank and so the filter in CLdap.php will be created as "(sAMAccountName =....) which then fails.

Wouldn't it be a good idea to "trim" such strings?
