Ldap auth stopped working after OS update

tizo

After updating the OS (CentOS Stream release 8) of the host with osticket, LDAP auth stopped working. I tried deleting LDAP Authentication and Lookup plugin, and adding it again, with the same old values, but all that says now is "Unable to connect any listed LDAP servers".

I know that is not a network issue, as I could test the connection successfully:

# nc -zvw3 freeipa.fi.xx.xx.xx 636 Ncat: Version 7.70 ( https://nmap.org/ncat ) Ncat: Connected to 10.x.x.x:636. Ncat: 0 bytes sent, 0 bytes received in 0.01 seconds.
PHP major and minor version are the same as before the OS update; only the release number has changed (from 7.4.21 to 7.4.29).

Details about osticket:

Any help is appreciated. Thanks.

Probably SELinux or something blocking the port, connection, etc. Check from CLI to see if you can make a connection to AD and do a lookup. Regardless you should look at all your logs for any related errors.
