The invention discloses a single sign-on
server. The single sign-on
server comprises a memory and a processor; a single sign-on program which can be run in the processor is stored in the memory. Whenthe program is carried out by the processor, steps below are realized: obtaining a sign-on request sent from a
client to the
server based on a reorientation information sent by a
service system; obtaining account information from the sign-on request, obtaining a
system identifier of the
service system and an associated white
list from the reorientation information and judging whether account information exists in the white
list; if so, verifying the account information and a
password in the sign-on request; if the
verification passes, returning token information to the
client for storage and storing the token information after the token information is associated with the account information of the
client. The invention also provides a single sign-on method and a computer readable storage medium. According to the single sign-on server, the single sign-on method and the computer readable storage medium, a
system code amount is reduced, the
system reusability is improved, and centralizedmanagement of each
service system authority in the single sign-on system is realized.
