The Security ID is not valid causes memory leak in Ldap

Question

Hi, all:
We are using the Novell LDAP Provider to allow our server application
be configured in LDAP mode. One of our clients is experiencing a memory
leak and we believe that the problem could be related to a "The Security
ID is not valid" error. When he changes to native Active Directory mode
the memory leak dissapears (he still gets the "Security ID" error, but
all works fine). So, we think that the problem caused by the "Security
ID" error is affecting the Novell Ldap Provider library. He is using a
Windows 2008 R2 platform.
My question is: Do you know if these kind of errors are properly
handled so that resources are released?
We are using the 2.1.10.1 version of the library.
Many thanks for you help,
Luis
