Consider the following scenario:
In this scenario, the LDAP Login Expression string comparison may become case-sensitive. Then, when a user provides a string such as user@Contoso.com, the string may not match the LDAP Login Expression.
Note This works as expected and is case-insensitive when only one wildcard character is used in the LDAP Login Expression.
This problem occurs because the LDAP Login Expression code incorrectly uses case-sensitive string comparisons when multiple wildcard characters are used.
