Emulation of federative authentication

A non-transitory machine-readable storage medium comprising instructions for accessing a target entity in a target domain based on authentication federation between a source domain and the target domain, the instructions upon execution causing a user device in the source domain to:

• receive, from a source federation site of the source domain, an authentication token for use at a target federation site of the target domain, the authentication token being from a user memory that correlates the authentication token to first user credentials useable in the source domain;
• send, to the target federation site, the authentication token;
• receive, by the user device from the target federation site, a request authentication token from a second memory that correlates the authentication token to the request authentication token;
• send the request authentication token to an authentication federation emulator that comprises an emulator memory correlating the request authentication token and second user credentials useable in the target domain;
• receive, responsive to the sending of the request authentication token to cause approval of the request authentication token by the authentication federation emulator, the second user credentials from the emulator memory of the authentication federation emulator;
• and
• use the second user credentials received from the authentication federation emulator to access the target entity in the target domain.

A user device of a source domain, comprising:

• a processor;
• and
• a non-transitory storage medium storing instructions to access a target entity in a target domain based on authentication federation between the source domain and the target domain, the instructions executable on the processor to:
• receive, from a source federation site of the source domain, an authentication token for use at a target federation site of the target domain, the authentication token from a user memory that correlates the authentication token to first user credentials useable in the source domain;
• send, to the target federation site, the authentication token;
• receive, by the user device from the target federation site, a request authentication token from a second memory that correlates the authentication token to the request authentication token;
• send the request authentication token to an authentication federation emulator that comprises an emulator memory correlating the request authentication token and second user credentials useable in the target domain;
• receive, responsive to the sending of the request authentication token to cause approval of the request authentication token by the authentication federation emulator, the second user credentials from the emulator memory of the authentication federation emulator;
• and
• use the second user credentials received from the authentication federation emulator to access the target entity in the target domain.
