[Fedora-directory-users] Help needed migrating from Sun ONE to Fedora DS 1.1

[Christopher Waltham]

I'm reasonably new to LDAP and very new to Fedora's DirectoryServer.  
I'm trying to "migrate" (I use the term loosely) from a Sun ONE  
(specifically, JES 2004Q2, which is Directory Server 5.2) LDAP server  
to a Fedora Core 8 server running DS 1.1.0 (installed from a yum  
respository's binary).

My problems are twofold: I have custom schema authored by Bowdoin (a  
college, my employer), and I have schema that comes from Sun's  
implementation of LDAP. For example, on the Sun server, 99user.ldif  
contains the following:

objectClasses: ( nsmsgCfgmtaautoreplyhandler-oid NAME  
'nsmsgCfgmtaautoreplyhan
  dler' SUP top STRUCTURAL MUST cn MAY ( nsmsgDefaultecho $  
nsmsgDefaultreply
  $ nsmsgDefaultvacation ) X-ORIGIN ( 'iPlanet Messaging Server  
configuration'
   'user defined' ) )

(which is for iPlanet, a part of Sun's... well, whatever)

As well as:

attributeTypes: ( majorname-oid NAME 'majorname' DESC 'Major Full  
Name' SYNTAX
   1.3.6.1.4.1.1466.115.121.1.15 X-ORIGIN 'user defined' )

Which is used to track students' majors. I tried following the  
instructions I found here:
http://www.redhat.com/docs/manuals/dir-server/MigrateFromSun.html 
  and "converting" the 99user.ldif file into a more typical LDIF and  
adding that with ldapmodify, but that didn't work particularly well --  
a lot of the Sun-specific schema was rejected by Fedora DS. Then I  
tried removing what I thought was the Sun schema extensions leaving  
Bowdoin's extensions, and that seemed to work (with one or two strange  
exceptions).

However, when I tried to import the LDIF full of users from the Sun  
system (which I dumped with db2ldif), I get a whole host of errors:  
mostly things like "Error adding object 'dn:  
cn=Administrators,o=Bowdoin College,c=US'.  The error sent by the  
server was 'Object class violation. attribute "mgmanmembervisibility"  
not allowed". I'm no expert, but I presume this is because the LDIF of  
users still contains references to the Sun schema attributes. So, here  
are my questions:

* why can't I import the Sun schema if that's what I want to do?
* if I can't import the Sun schema, is there an easy way of stripping  
out the Sun attributes from a 10,000-user LDIF file?

Thanks,


Chris

You should
be able to do that.  It's really odd that Sun defined schema 
is in 99user.ldif - that file is reserved solely for user defined schema 
added via LDAP.  You'll have to post the errors here so we can address 
the issues.

If you are a Perl hacker, you
could use Mozilla perldap (included with 
the fedora ds software) or Net::LDAP (probably bundled with your linux 
OS perl distribution).  If you prefer python, python-ldap also has an 
LDIF parser.

I did one better: I simply copied the entire config/schema/ directory  
from the Sun box to the Fedora box, and tried to restart Fedora DS. I  
got some non-fatal errors:

[root@hebron slapd-hebron]# /etc/init.d/dirsrv start

That gave me some hope, so then I tried to import my database from an  
LDAP. FWIW, this is how I generated the LDIF on the Sun box:

db2ldif 'o=Bowdoin College, c=US'

Then I just tried this in Fedora:

/usr/lib/dirsrv/slapd-hebron/ldif2db -s 'o=Bowdoin College, c=US' -i / 
path/to/dumpfile.ldif

And I got the following errors:

To be honest, I am a little confused at the relationship between  
instances and backends. From what I can see, Sun includes the  
following instances: userRoot, internetdb, pab and netscapeRoot (and  
possibly others?). But, I only have one suffix that I need, which is  
o=Bowdoin College, c=US.

It would
probably be better to only copy the files not already in the 
Fedora DS schema directory e.g. pseudocode

for file in sun/config/schema/*.ldif
  name=`basename $file`
  if [ ! -f /etc/dirsrv/slapd-instancename/schema/$name ] ; then
    cp $file /etc/dirsrv/slapd-instancename/schema/$name
  fi
done

Because the Fedora DS schema has changed someone.  For starters, our new 
00core.ldif contains only the very core essential schema required to 
start the server - the non-essential schema has been moved to 
01common.ldif.  Their 00core.ldif probably still contains everything.  
So if you overwrite the fedora ds 00core.ldif with theirs, chaos will ensue.

You might try the migrate-ds-admin.pl script.  It might be
able to 
handle the Sun data.  Use -o /opt/iplanet or whatever they use for their 
server root directory.

If migration does not work, then you will at least have to create a 
database and configure a suffix for o=Bowdoin College, c=US

Also you may not even need to copy the SUN schema unless you really
need it. Use the default FDS schema and then add your custom schema.
Then import some data, if your just importing common objects they
might not even require that schema.

python-ldap also has a schema parser with which you could follow 
cross-references between schema elements programmatically...

Ciao, Michael.
