我正在进行Liferay和alfresco的整合，我的目标是使用alfresco 5.2来存储在Liferay DXP中创建的内容。
为此，我已将此行添加到portal-ext.porperties
dl.store.impl=com.liferay.portal.store.cmis.CMISStore
并添加了包含以下内容的配置文件com.liferay.portal.store.cmis.configuration.CMISStoreConfiguration.cfg：
repositoryUrl=http://localhost:8080/alfresco/api/-default-/public/cmis/versions/1.1/atom
credentialsUsername=admin credentialsPassword=password
systemRootDir=Liferay
一切正常但突然在重启liferay时出现此错误：
21:19:37,536 ERROR [localhost-startStop-1][com_liferay_portal_store_cmis:97] [com.liferay.portal.store.cmis.CMISStore(1549)] The activate method has thrown an exception

在这种情况下，未授权意味着什么？
