YL-T2x : ldap search

[Yealink Support]

Hi Jonas,
Is there any problems when you search on the phone, except the LDAP-server log shows these unknown filter ?
I am afraid we need your phone logs to find out the problem.
So could you provide PCAP trace, syslog(level 6) and config.bin file to us, so we can analyze?
Before you export the syslog, please set log level as 6, and reboot the phone, then click Start,and reproduce the issue, then click Stop,and export the trace, syslog, config,bin to us.
(About where to export these files, please refer to attached screenshot.)
These three files are very important for us, hope you can kindly understand.
Thanks.
