Ew, PHP :P
Yes, I noticed the UDN was missing as well. That's necessary. I wrote a
python script to pull accounts from the old ldap directory and migrate
various attributes (including the UPN) to the AD accounts, following
this LDIF template:
template = '''\
dn: CN={uid[0]},{new_container}
changetype: modify
replace: givenName
givenName: {givenName[0]}
-
replace: sn
sn: {sn[0]}
-
replace: userPrincipalName
userPrincipalName: {uid[0]}@{new_realm}
dn: CN={uid[0]},{new_container}
changetype: modrdn
newrdn: CN={givenName[0]} {sn[0]}
deleteOldRdn: 1
'''
So I ended up with LDIF that looked like (for example):
#uid=michael,ou=people,dc=netdirect,dc=ca
dn: CN=michael,OU=Net Direct,OU=Staff,DC=ad,DC=netdirect,DC=ca
changetype: modify
replace: givenName
givenName: Michael
-
replace: sn
sn: Brown
-
replace: userPrincipalName
userPrincipalName: michael at ad.netdirect.ca
dn: CN=michael,OU=Net Direct,OU=Staff,DC=ad,DC=netdirect,DC=ca
changetype: modrdn
newrdn: CN=Michael Brown
deleteOldRdn: 1
