Exchange 2000 or 2003 running in Native mode in a W2K AD.
Regular users with no rights to modify ad security groups have the ability
to change a distribution list to a security group.
Steps to recreate problem.
1: User opens a mailbox with Outlook 2000 / XP / 2003
2: Navigates to mailbox permissions
3: Add distribution list from Gal access as contributor.
4: Save changes
Once the user adds the distribution list Exchange will convert the
distribution list to a like security group
for example if you have a All_Users universal distribution list Exchange
will convert to a Universal Security group.
This can cause some serious Kerberos issues if you are running close to the
Kerberos key size limits.
Has anyone come across this and if so have they found a solution to stopping
NTBugtraq Editor's Note:
Want to reply to the person who sent this message? This list is configured such that just hitting reply is going to result in the message coming to the list, not to the individual who sent the message. This was done to help reduce the number of Out of Office messages posters received. So if you want to send a reply just to the poster, you''ll have to copy their email address out of the message and place it in your TO: field.
