Abstract

A system and method for DEN/LDAP client database access with backoff capability. A current tree of directory information maintained at an LDAP server is used by LDAP clients to retrieve policy configuration information. When an LDAP client wishes to update policy configuration information, a new tree is created by cloning the current or a previous tree or by building a new tree. When the LDAP client is finished updating the new tree, the path for using LDAP clients is set to the new tree and the clients are requested to read LDAP policy configuration information using the new path. If the new tree of policy configuration information is found to be unsuitable, the clients'"'"' path is reset to the original tree and the clients are requested to read LDAP information policies using the reset path.

Claims

1. A method for accessing information stored in a server directory in a client-server computer system comprising a server and a plurality of client devices connected by a computer network, the method comprising the steps of:

selecting an existing configuration from a list of configurations stored in the server directory;

replicating the existing configuration under a new branch of the server directory;

editing the replicated configuration to create a new configuration;

determining if an existing active configuration for a client device should be changed to the new configuration;

selecting the new configuration from the server directory;

changing the status of the active configuration for the client device to inactive in the server directory;

changing the status of the selected configuration for the client device to active in the server directory;

changing a configuration path name in the client device to the selected configuration; and

resetting the configuration path name in the client device to a previously active configuration if the selected configuration is determined to be defective.

2. The method of claim 1 further including the step of requesting the client device to refresh its configuration based on the reset configuration path name.

3. A computer program product adaptable for storage on a program storage media at a host machine in a client-server computer system comprising a server and a plurality of client devices connected by a computer network, the computer program product operable in conjunction with a first client device for accessing information stored in a server directory, the computer program product comprising:

program code for selecting an existing configuration from a list of configurations stored in the server directory;

program code for replicating the existing configuration under a new branch of the server directory;

program code for editing the replicated configuration to generate a new configuration;

product code for determining if an existing active configuration for a client device should be changed to the new configuration;

product code for selecting the new configuration;

product code for changing the status of the active configuration for the client device to inactive in the server directory;

product code for changing the status of the selected configuration for the client device to active in the server directory;

product code for changing a configuration path name in the client device to the selected configuration; and

program code for resetting the configuration path name in the client device to a previously active configuration if the selected configuration for the client device is determined to be defective.

4. The computer program product claim of claim 3 further including program code for requesting the client device to refresh its configuration based on the reset configuration path name.

5. A system for accessing information stored in a server directory in a client-server computer system comprising a server and a plurality of client devices connected by a computer network, the system comprising:

a user interface for selecting an existing configuration from a list of configurations stored in the server directory;

means for replicating the existing configuration under a new branch of the server directory;

a user interface for editing the replicated configuration to create a new configuration,;

means for determining if an existing active configuration for a client device should be changed to another selected configuration;

a user interface for selecting a new configuration from the server directory;

a user interface for changing the status of the active configuration for the client device to inactive in the server directory;

a user interface for changing the status of the selected configuration for the client device to active in the server directory;

a user interface for changing a configuration path in the client device to the selected configuration; and

means for resetting the configuration path name in the client device to a previously active configuration if the selected configuration for the client device is determined to be defective.

6.The systen of claim 5 further including means for requesting the client device to refresh its configuration based on the reset configuration path name.
