getdomains
Getdomains retrieves all domains from the user authentication database table used by the login command.

In work environments where a user might have different access rights depending on the branch of the institution he or she is trying to access data in, and a user authentication web service is in effect, domains may be in use by the institution to separate these access rights. Getdomains
simply retrieves the domains stored in a special domain field in the authentication database table of the institution.

Syntax
command=getdomains
Examples

In this case, only one domain "MUSEUM" has been registered.
