题外记
在文档《Cognos(R) 8 Administration and Security Guide》中提到
Systems Administrator(用户管理员)
This is a special role. Members of this role are considered root users or super users. They may access and modify any object in the content store, regardless of any security policies set for the object. Only members of the System Administrators role can modify the membership of this role.
所以一定要System Administrators的用户才可以删除System Administrators里的用户,而且System Administrators里最少要有一个成员存在。
