I have installed a trial version of SAM 6.4 on Windows Server 2012. I have configured LDAP authentication. First of all, to get this to work, I had to turn off LDAP authentication, which is a little confusing for me. Anyway, somehow, it is working now. But now, there is another problem. The login doesn't work the first time and it does not give any error also sometimes in the logs, but it works the 2nd time. This is applicable even for the admin user (without password). To workaround this issue, I tried a setting, which is Enable Anonymous authentication at the level of the IIS website for the Orion Web Console. After this setting, the issue got resolved. Is this correct? If not, can anyone please provide a solution for this issue?
