Hi All,
Following the link, tried to migrate NT4 to AD using LDAP but came across some
issues.
https://wiki.samba.org/index.php/Migrating_a_Samba_NT4_Domain_to_Samba_AD_(Classic_Upgrade)
I have done this step multiple times using TDB as the backend and it has always
worked.
The issue I am seeing is when I run the following, we get
samba-tool domain classicupgrade --dbdir=/var/lib/samba.PDC/dbdir
--realm=LIN.GROUP --dns-backend=SAMBA_INTERNAL /etc/samba.PDC/smb.PDC.conf
Next rid = 10003
ERROR(<type 'exceptions.IndexError'>): uncaught exception - list
index out of range
File "/usr/lib/python2.7/dist-packages/samba/netcmd/__init__.py",
line 175, in _run
return self.run(*args, **kwargs)

in upgrade_from_samba3
urls = samba3.lp.get("passdb
backend").split(":",1)[1].strip('"')
I'm running the upgrade on PDC (LDAP) server .
local master = yes
domain master = yes
preferred master = yes
domain logons = yes
os level = 65
#LDAP
passdb backend = ldapsam
ldap admin dn = cn=admin,dc=lin
ldap suffix = dc=lin
ldap group suffix = ou=groups
ldap machine suffix = ou=computers
ldap user suffix = ou=users
idmap backend = ldap
ldap idmap suffix = ou=idmap
idmap config *: backend = ldap
idmap config *: range = 10000-19990
idmap config *: ldap_url = ldap://lin-pdc.lin/ (Also tried //localhost)
idmap config *: ldap_base_dn = ou=idmap,dc=lin
idmap config *: ldap_user_dn = cn=admin,dc=lin
ldap delete dn = yes
ldap password sync = yes
The only thing I can think of is when running the smbldap-popluate we used the
following,
smbldap-populate -g 10000 -u 10000 -r 10000
Samba version 4.6.7 (Ubuntu 16.04)
Can anyone please advise?

Praveen Ghimire

In the short term, try changing the 'passdb backend' line in smb.conf to this: passdb backend = ldapsam:"ldap://lin-pdc.lin/" Rowland
Hi Rowland, I did that initially and that came with Failed to connect to ldap URL 'ldap://lin-pdc.lin - LDAP client internal error: NT_STATUS_BAD_NETWORK_NAME Hence I removed the whole ldap:// bit After your email I tried again but using ldap://localhost and it seems to have worked. Not sure what the issue is with the fqdn. I could run ldap queries when using fqdn.
