have root or system admin access can you try to login the LDAP user using this functionality . 2. Also if you go on the details screen for the LDAP User asset and can double check the username you are using and compare it to the one appearing on the screen. I have seen a couple of time the user name appearing on that screen isn't the same as being used by the user. Ash Hi again, Ash, and thanks again for your help, 1. I do indeed have System Admin access. However, it still won't let me Switch Users to my LDAP user account. When I click on the "Login As" button and put in my LDAP User name, it takes me to the usual login screen. And when I attempt to login there with my LDAP User name and password, I still get the same old "Invalid username or password entered" message in red. 2. The Details screen for my LDAP User asset doesn't really show the username I'm using, although the asset as shown in the asset map includes my username, and various other attribues (CN, OU and DC0). My username as displayed there starts with a capital letter followed by all lower case letters. I've tried it with and without the first letter capitalised, and still to no avail. So, still no joy, basically. (I should mention, at this stage, I've only given the LDAP users Write Permission - and not Read or Admin Permission -
