Spring Security manually setting authentication without authentication manager giving error -


i setting authentication manually in application using preauthenticatedauthenticationtoken. keep getting error follows,

no bean named 'org.springframework.security.authenticationmanager' defined: did forget add gobal element configuration (with child elements)?

i don't have userdetailsservice not required me. please me on how configure authentication manager ?

you missing <authentication-manager> element. need have 1 processes preauthenticatedauthenticationtoken, adding relevant roles user. if want no-op operation, that's fine, still has there, can either implement simple userdetailsservice returns user object fixed role, or can implement authenticationprovider directly , create final token in authenticate method, want it. either way, configuration similar the 1 described in user manual.
