A computer-implemented method for managing enterprise data, the method comprising: creating, by a number of processors, a human resources, HR, database; creating, by the number of processors, a lightweight directory access protocol, LDAP, interface in communication with the HR database and a number of third party heterogeneous external directories, wherein the HR database is the source of truth for the external directories, wherein each external directory has a respective protocol that differs from protocols of other heterogenous external directories, wherein the LDAP interface serves as a proxy for requests between the number of third party heterogenous external directories and the HR database, wherein the LDAP interface maintains authorization credentials with the number of third party heterogenous external directories; managing and synchronizing, by the number of processors, user data through the LDAP interface across the number of third party heterogeneous external directories using the LDAP protocol, wherein the LDAP interface: authenticates a client system using an LDAP bind operation, parses a request from the client, initiates an LDAP bind operation with the number of third party heterogenous external directories, prepares the LDAP root directory to access the data cache in one of the external directories, submits an LDAP query to the external directory; wherein the external directory, in response to said query, searches for client request data in the data cache and, if not found, adds the missing data to the data cache, and sends a response denoting that the external directory has been updated; wherein the LDAP interface unbinds from the client when there is no more data to update and synchronize across the external directories. creating, by a number of processors, a human resources, HR, database; creating, by the number of processors, a lightweight directory access protocol, LDAP, interface in communication with the HR database and a number of third party heterogeneous external directories, wherein the HR database is the source of truth for the external directories, wherein each external directory has a respective protocol that differs from protocols of other heterogenous external directories, wherein the LDAP interface serves as a proxy for requests between the number of third party heterogenous external directories and the HR database, wherein the LDAP interface maintains authorization credentials with the number of third party heterogenous external directories; managing and synchronizing, by the number of processors, user data through the LDAP interface across the number of third party heterogeneous external directories using the LDAP protocol, wherein the LDAP interface: authenticates a client system using an LDAP bind operation, parses a request from the client, initiates an LDAP bind operation with the number of third party heterogenous external directories, prepares the LDAP root directory to access the data cache in one of the external directories, submits an LDAP query to the external directory; wherein the external directory, in response to said query, searches for client request data in the data cache and, if not found, adds the missing data to the data cache, and sends a response denoting that the external directory has been updated; wherein the LDAP interface unbinds from the client when there is no more data to update and synchronize across the external directories. authenticates a client system using an LDAP bind operation, parses a request from the client, initiates an LDAP bind operation with the number of third party heterogenous external directories, prepares the LDAP root directory to access the data cache in one of the external directories, submits an LDAP query to the external directory; wherein the external directory, in response to said query, searches for client request data in the data cache and, if not found, adds the missing data to the data cache, and sends a response denoting that the external directory has been updated; wherein the LDAP interface unbinds from the client when there is no more data to update and synchronize across the external directories.
