client authentication with Active Directory LDAP ???

I haven't tried configuring client auth against AD, but I have done admin auth. If you're getting auth failures, you might try capturing tcpdumps between LTM and the AD server, and viewing them in Wireshark. Wireshark will help you with protocol analysis of the LDAP traffic. You can compare your working ldapsearches from the command line with the actual queries LTM makes based on the auth config.

 

 

If this doesn't help and you don't get an answer on the specific formats for the AD config, you could also try opening a case with F5 Support and ask for an example AD client auth configuration.
