After a fresh install of portal, using the admin/7layer credentials does not let you login.
Add the following line in /etc/my.cnf and then restart mysql:
lower_case_table_names=0 (Case Sensitive Enabled)
lower_case_table_names=1 (Case Sensitive Disabled)
Table names are stored in lowercase on disk and name comparisons are not case sensitive. MySQL converts all table names to lowercase on storage and lookup. This behavior also applies to database names and table aliases.
