For example, when authenticating using LDAP, if the request uses a username "FOO", Artifactory won't be able to use the non-ui authentication cache. This happens due to the fact that Artifactory normalizes usernames (with toLower) and we get confused about other casing variations if they are used (i.e FOO != foo => so no cache).
1.Connect artifactory to LDAP
2.Authenticate using uppercase letters for the username
3.Observe how Artifactory always goes out to LDAP to authenticate the user.
