A computer network adapted to provide secured access to applications for a user, said computer network comprising: at least one application server hosting a plurality of applications (10.1,...,10.n), said at least one application server being adapted to receive an access request emitted by the user and to grant access to at least one of the plurality of applications (10.1,...,10.n); a login security server configured for deciding access for the user based on data contained in a central generic access control file and in the access request; said computer network further comprising a centralized user identification component adapted to interface with the at least one application server of the network and the login security server, said at least one application server being configured to transmit the access request to the centralized user identification component, said access request comprising a list of at least one requested application (10.1,...,10.n); and said centralized user identification component is configured for: receiving the transmitted access request; displaying a central login panel to the user, said central login panel being adapted according to the at least one requested application (10.1,...,10.n); receiving identification data of the user from the central login panel; transmitting said identification data and the list of at least one requested applications (10.1,...,10.n) to the login security server; retrieving from the login security server an access grant or denial command for each of the at least one requested application (10.1,...,10.n); sending said access grant or denial command to the at least one application server. at least one application server hosting a plurality of applications (10.1,...,10.n), said at least one application server being adapted to receive an access request emitted by the user and to grant access to at least one of the plurality of applications (10.1,...,10.n); a login security server configured for deciding access for the user based on data contained in a central generic access control file and in the access request; said computer network further comprising a centralized user identification component adapted to interface with the at least one application server of the network and the login security server, said at least one application server being configured to transmit the access request to the centralized user identification component, said access request comprising a list of at least one requested application (10.1,...,10.n); and said centralized user identification component is configured for: receiving the transmitted access request; displaying a central login panel to the user, said central login panel being adapted according to the at least one requested application (10.1,...,10.n); receiving identification data of the user from the central login panel; transmitting said identification data and the list of at least one requested applications (10.1,...,10.n) to the login security server; retrieving from the login security server an access grant or denial command for each of the at least one requested application (10.1,...,10.n); sending said access grant or denial command to the at least one application server. receiving the transmitted access request; displaying a central login panel to the user, said central login panel being adapted according to the at least one requested application (10.1,...,10.n); receiving identification data of the user from the central login panel; transmitting said identification data and the list of at least one requested applications (10.1,...,10.n) to the login security server; retrieving from the login security server an access grant or denial command for each of the at least one requested application (10.1,...,10.n); sending said access grant or denial command to the at least one application server.
