org.hibernate.HibernateException: Missing sequence or table: 序列名称

最近在开发单点登录CAS时，将默认内存存放票据改为了数据库存放，CAS本身支持的，结果报下面的错误：

SEQ_UM_RS这个序列名是我后来修改的，原本使用的是HIBERNATE默认的HIBERNATE_SEQUENCE,但由于我们其它系统已经有在使用这个序列了，所以需要重新创建一个。
我们的数据库用户有两个，一个是XXDATA用户，一个是XXOPR用户，前者用于管理相关表的创建，权限较大，后者只有相关的使用权限，表的URD等。
SEQ_UM_RS序列是用XXDATA用户创建的，然后创建同义词，再授权给XXOPR用户，一切都很正常，但是程序在布署后就报上面的错误。

最终查找原因为HIBERNATE方言设置的问题
org.hibernate.dialect.OracleDialect设置为这个时会报错
org.hibernate.dialect.Oracle10gDialect设置为这个时则正常
原因有可能OracleDialect不支持间授权，再使用同义词的方式。
