Fixed In Version: nss_ldap-253-25.el5_5.1 Doc Type: Bug Fix
Doc Text:
When using pluggable authentication modules (PAM), selected modules can be loaded and unloaded upon each authentication attempt. However, unloading the pam_ldap module could cause the memory that is allocated by libraries on which it depends to be lost. Consequent to this, multiple authentication attempts may have led to a significant memory loss. To prevent this, the pam_ldap module is no longer unloaded.
