Just got fresh trial version of LTM and wonder why I got only one Authentication profile type available which is SSL Client side certificate? Is this somewhat limitation of Trial version or something went wrong with my setup? Tried to google it with no success, so maybe someone here had same case?
I believe you're referring to the old "ACA" or Advanced Client Authentication feature module that included LDAP, TACACS, Kerberos, OCSP/CRLDP, etc. I don't believe that module is available anymore, and the remaining certificate auth pieces have been migrated directly into LTM. To do LDAP you now need APM.
I'd assume other options would only be available with APM.
ACA is now EOL and no longer an option on LTM - https://support.f5.com/csp/article/K14263
I think you need to go to APM for similar functionality?
