The LDAP Tool Box project provides a set of LDAP-related applications, administrative tools, and other utilities. They have just released the 0.3 release of their Service Desk tool, which is a web application for administrators that supports viewing and managing accounts in an LDAP directory server. This release includes the following changes:

• Added support for locking accounts by setting a specific value in the pwdAccountLockedTime attribute
• Fixed an issue in which it did not properly handle the case in which the pwdAccountLockedTime attribute was set but pwdLockoutDuration was missing or zero

Note that because these operations are not standardized, they will only be available for certain types of directory servers.
