Hello,

I've set up OSticket 1.14.3 on Ubuntu 20.04 with PHP 7.4 & MySQL 8.0.
I'm having a hard time to get the LDAP plugin to work to authenticate the clients. I've used the following settings in LDAP plugin:

• Default domain: company.com
• DNS server : <IP domain controller>
• LDAP servers: <IP domain controller> (without :port)
• Use TLS : yes
• Search User: CN=<NAME>;OU=Users,OU=affiliate,DC=company,DC=com
• password: pw of search user
• Search base: OU=Users,OU=affiliate,DC=company,DC=com
• LDAP schema = LDAP
• staff & client authentication both checked

HTTP passthru plugin is also enabled.

When I try to log in with my LDAP user, I get the following event log in my domain controller:

An account was successfully logged on.

Subject:
Security ID: SYSTEM
Account Name: <HOSTNAME DOMAIN CONTROLLER>$
Account Domain: <COMPANY>
Logon ID: 0x3E7

Logon Information:
Logon Type: 3
Restricted Admin Mode: -
Virtual Account: No
Elevated Token: Yes

Impersonation Level: Impersonation

New Logon:
Security ID: COMPANY\LDAP USERNAME
Account Name: LDAP USERNAME
Account Domain: VYNCKE
Logon ID: 0x7993604C
Linked Logon ID: 0x0
Network Account Name: -
Network Account Domain: -
Logon GUID: {00000000-0000-0000-0000-000000000000}

Process Information:
Process ID: 0x238
Process Name: C:\Windows\System32\lsass.exe

Network Information:
Workstation Name: HOSTNAME DOMAIN CONTROLLER
Source Network Address: IP OSTICKET
Source Port: 34602

Detailed Authentication Information:
Logon Process: Advapi

Authentication Package: MICROSOFT_AUTHENTICATION_PACKAGE_V1_0
Transited Services: -
Package Name (NTLM only): -
Key Length: 0

Immediately followed by the following event:

An account was logged off.

Subject:
Security ID: COMPANY\LDAP USERNAME
Account Name: LDAP USERNAME
Account Domain: COMPANY
Logon ID: 0x7993604C

Logon Type: 3

This event is generated when a logon session is destroyed. It may be positively correlated with a logon event using the Logon ID value. Logon IDs are only unique between reboots on the same computer

In OSticket I receive an Access Deniederror

How can I resolve this error? I've installed all necessary php modules etc.:
