I'm using LDAP authentication however disabling NTLMv1 on DC seems to generate problem and I can see in logs "Account logon with misspelled or bad password". Question is: how to configure LDAP on ADC to use force NTLMv2?

I think the NTLMv1 is disabled by default on later versions https://docs.netscaler.com/en-us/citrix-adc/current-release/aaa-tm/single-sign-on-types/enable-sso-for-auth-pol.html
