Need msDS-PrincipalName Attribute

[Scott Jordahl]

I have a 3rd-Party app that is requesting the "msDS-PrincipalName" 
attribute from the Samba AD. msDS-PrincipalName is labeled as a 
"Constructed" attribute (<domain>\<login name>) and I cannot manually 
modify the entry by using either the MS LDAP tools or via phpldapadmin.  
I need help trying to figure out if I can add the code to auto-generate 
this attribute or a way I can override the read-only flag so I can edit 
it manually.  I have a short list of users that need this attribute set, 
so if I can enter them in manually if I have the ability. If via new 
code, I need a hint on where to look and where it should be added. Of 
course, if I'm going at this totally wrong, then please point me in the 
right direction.

Thanks for the help!
