Technologies are generally described for automatically reconnecting a security principal to cloud services through correlation of security principal identifier attributes. A new security principal for a user may be detected and automatically reconnected to the user's cloud based services. An administrator for the security domains may specify a value of a unique security principal metadata attribute for the original security principal in a customizable security principal metadata attribute in the new security principal in the same or new security domain. A secondary verification metadata attribute may optionally be specified to ensure the correct security principal is reconnected to the user's cloud based resources. The correlation between the original security principal for the user and the new security principal may be used to reconnect the user's cloud resources.
