Problem browsing LDAP with Outlook
by Chris Bryant
When configuring Microsoft Outlook (not Outlook Express) to access an LDAP directory, there is an option to 'Enable Browsing (requires server support)'. If this option is chosen and the directory server supports it, then you should be able to open the LDAP address book and page up and down through the results. I have been unable to get this working properly with 389 DS.
When I try to browse from Outlook against the 389 DS directory, I am able to see the first page of results perfectly. However, if I move to the next page, only the first object returned will have any attributes included, and all of the rest of the objects in the page will have no attributes. I have a test perl script that duplicates this functionality as well.
I can get this to work properly with an older version of Netscape Directory Server, and I can get it working with OpenDS. Since 389 DS advertises support for the controls that are required for this to work, just like the other two servers, then I would expect it to work there also.
Has anyone out there gotten this to work with 389 DS? If so, can you share if there was anything special that you needed to do to get this to work? I'm trying to determine if this is a bug in the server, or if I'm just missing something in the configuration.
Thanks,
Chris

As far as encrypting it in the changelog - not sure

Hi,
Description of problem:
When a userPassword is changed in a server with changelog, the hashed password
is logged and also a cleartext pseudo-attribute version. It looks like this:
change::
replace: userPassword
userPassword: {SHA256}vqtiN2LHdrEUOJUKu+IBVqAVFsAlvFw+11kD/Q==
-
replace: unhashed#user#password
unhashed#user#password: secret12
This unhashed version is used in winsync where the cleartext version of the
password must be written to the AD.
Now if the DS is involved in replication with another DS, the change will be
replayed exactly as it is logged to the other DS replicas, including the
cleartext pseudo-attribute password.
What platform? What version of 389-ds-base are you
using?
thanks,
Denise

389 Master - Master Replication
by Santos Ramirez
Good Morning,
We have a master - master replication agreement. When we initialize the replication it works perfectly we can see changes to a test user we have set up go up and down from the two servers. However at some point the replication stops and we cannot get replication to start once again. The only way we can get replication to start once again is to recreate the replication agreement and then it fails again. Can anyone please point us in a direction. I am relatively new to 389 so any help would be greatly appreciated.

Netscape Portable Runtime error -5982
by Paolo Barbato
After a while I start again to work on 389 ds.
389ds last released from epel, is installed on a rhel 6.5, that host also other services (bind, dhcpd, radius.....). Such server is configured with some virtual nic.
I noticed starting 389ds the following error:
intranet5...[14/Feb/2014:08:30:20 +0100] createprlistensockets - PR_Bind() on All Interfaces port 636 failed: Netscape Portable Runtime error -5982 (Local Network address is in use.)
I've tried to insert in dse.ldif directives like
nsslapd-listenhost: 192.168.60.23
nsslapd-securelistenhost: 192.168.60.23
but it comes a more "IP specific" error :
intranet5...[14/Feb/2014:10:01:34 +0100] createprlistensockets - PR_Bind() on 192.168.60.23 port 636 failed: Netscape Portable Runtime error -5982 (Local Network address is in use.)
finally I noticed:
[root@intranet5 dirsrv]# netstat -anp | grep 636
udp 0 0 0.0.0.0:636 0.0.0.0:* 1342/portreserve
such service clearly conflict with 389ds ldaps
It seems I'm facing bug https://bugzilla.redhat.com/show_bug.cgi?id=848414
since I really have tested also openldap
[root@intranet5 dirsrv]# more /etc/portreserve/slapd
ldaps
from portreserve man I read
For each service configuration file, a socket is created and bound to the appropriate port. A service wishing to bind to its port must first run portrelease, which instructs
portreserve to release the port associated with the service.
It seems so that 389ds be not aware of portreserve . Shoud I simply remove /etc/portreserve/slapd and restart portreserve ?
Regards,
Paolo.

Windows sync agreement - Received result code 34
by Vesa Alho
Hi,
I'm trying to get Windows AD sync working. When trying to start full
re-syncronization, I get the errors listed below. I've tried to verify
all settings, but haven't figured out what could cause this. It seems to
use value (null) with DN, but why?
Other information:
389 => 1.2.11.25 (dc=example,dc=com)
AD => Windows 2012 R2 (dc=example,dc=login)
==> notice, domain names are different!
Windows sync agreement details
Windows domain: example.login
DS subtree: ou=People,dc=example,dc=com
Windows subtree: cn=People,dc=example,dc=login
Replicated subtree: dc=example,dc=com
My goal is to sync 389 users to one OU/CN under AD and groups to
different OU/CN. I'm not sure if this even possible, but was hoping to
achieve this by creating separate sync agreements for users and groups.
PS. thanks for excellent software and support!

Serious write-performance problems on RHEL6
by Steve Holden
Hi, folks
I'm hoping to use 389 DS to replace our ancient Sun DS 5.2 service.
I've hit a snag with my 389 development server; it's performance far worse
than the 10 year-old servers it's intended to replace.
Things looked promising: the old directory data has been imported (with
only minor changes), read requests perform reasonably well, and isolated
write requests are ok.
However, even after a small number (typically 6) of consecutive write requests
(basic attribute changes to a single entry, say) the ns-slapd process hits >100%
CPU (of 2 CPUs) and stays there for *at least* 10 seconds per update, and blocks
the client process attempting the update.
I can't see anything obvious in the performance counters or the logs to suggest
a problem. The updates are logged with "etime=0" in the access log.
I've tried enabling different log levels in the error log.
Is it normal for the Plugin level to show constant re-scanning of CoS templates?
I'd be very grateful for any suggestions of how I can go about tracing where the
Problem might be and how to resolve it...
Best wishes,
Steve
Details
The RHEL6.5 server is a VMware ESXi VM with 8GB RAM and 2x CPUs,
and is running the latest EPEL package for RHEL6 (v1.2.11.15-32).
(After a package upgrade a few weeks ago, I ran "setup-ds-admin.pl -u").
The directory contains in excess of 200,000 entries, and
its databases consume over 3.5GB on disk.
The userRoot database has therefore been configured with a 4GB cache
(and the general LDBM max cache is set at 6GB - though it's quite possible
I haven't understood how to set these correctly - I've tried smaller numbers of each).
The directory contains custom attributes, some of which are CoS,
and many of which have been indexed (AFAIK, all attributes have been re-indexed).
No replication has been configured so far.

Operations Error on object
by Michael Gettes
389-Directory/1.2.11.15 B2013.238.2155 starting up
Linux 2.6.32-431.5.1.el6.x86_64 #1 SMP Fri Jan 10 14:46:43 EST 2014 x86_64 x86_64 x86_64 GNU/Linux
I have an object which I am unable to operate on. I try to modify it or delete it and I get err=1 (Operations Error).
it looks like:
[25/Mar/2014:13:13:00 -0400] conn=348 op=3 DEL dn="nsuniqueid=cf397a8e-b11f11e3-9e1cd834-1f7e47a1,CN=Community:ByOU:XXXX,ou=Groups,dc=XXX,dc=XXX"

Normally, the object is CN=Community:ByOU:XXXX,ou=Groups,dc=XXX,dc=XXX but when I search for
CN=Community:ByOU:XXXX,ou=Groups,dc=XXX,dc=XXX I get back the nsuniqueid as part of the DN (shown above).
I have dumped the LDIF and the nsuniqueid is NOT in the LDIF with this object.
I have restarted the server to no avail.
I have looked in bugzilla and can’t seem to find anything that looks like this problem.
I am confused and seeking advice. I am somewhat worried I have objects I cannot modify or delete. I have 2 of these now and I am not sure how they are getting into this state.
Any guidance is gratefully appreciated!

LAN vs WAN
by Amjad Farooq
Hi everyone,
I have TWO linux machines in my office. One is on LAN (only
locally-accessible) and the other on WAN (WWW-accessible). On the WAN, I
have an apache server running but I also mounted a hard drive from the LAN
machine using NFS so that I can easily access and transfer data files
between the two machines.
My question is:
Is the hard drive from the LAN machine mounted on the WAN computer
accessible from outside LAN? In other words, if an hacker breaks into my
server on the WAN machine, will (s)he be able to access data on my
NFS-mounted hard drive from the LAN machine? I would assume that since IP
assigned to my LAN machine is only accessible locally, access from outside
LAN to this hard drive will not be available. What do you think?
Thank you for your suggestions.

Problem when trying to perform dereference searches
by Jonathan Vaughn
We've had problems with SSSD being slow sometimes, but not others, and
there never seemed to be any obvious cause why, but I think I've tracked it
down to problems with dereferencing. We do see errors about dereferencing
in the log, but I didn't realize until now what it was referring to.
In theory, a search like this should give us the cn and objectclass of all
members of the group, but I get only the attributes of the group itself.
Whether I give the "-E 'deref=...'" or not I get the same output. Redacted
output below:
