I need some help with being able to correctly set up alfresco 5.0a on CentOS 6. I can install alfresco and make it to the share and alfresco pages (127.0.0.1:8080/share and /alfresco) but I get an error whenever I attempt to login. I have tried different combinations, using Postgresql 9.3 (with jdbc 9.3 connector), using the postgresql supplied with the alfresco installer, as well as mysql 5.1 (with jdbc 5.1 connector). For each of the database I have tried I have made the database and user and granted privileges to the user for the database. I don't understand what I am doing wrong here. Help would be greatly appreciated during this time.
