Problem browsing LDAP with Outlook
by Chris Bryant 26 Aug '20

26 Aug '20

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 USA.NET You Run Your Business. We'll Run Your Email.

MemberOf group restrictions to a client system (server and client running CentOS 7)
by Janet Houser 06 Aug '20

06 Aug '20

Hi, I'm new to 389-ds and last week downloaded and installed the software. I have a running instance of the server, and I've added TLS/SSL. I've configured a CentOS 7 client to be able to query the server using TLS/SSL, and all appears working. I've created users and groups on the 389-ds server successfully. For each user and group, I've enabled posix attributes and my client can see the unix users and groups using the "getent password" or "getent group" commands. Now, here's where I'm getting tripped up.......... I need to limit which users have access to which systems. I've been trying to do this via memberOf group limitations. I found the following online resource (https://thornelabs.net/2013/01/28/aix-restrict-server-login-via-ldap-groups…) which is close enough to CentOS that the initial commands worked. I enabled the MemberOf plugin and changed the attributes per the link, and restarted the system. I created a test group (that I didn't enable a posix GID) and tried to add a single user via: Right click on group -- > click Properties --> then Members --> click Add --> Search for user --> click Add. When I try to go this route (which worked before enabling the memberOf plugin) it worked. Now it seems I get the error: "Cannot save to directory server. netscape.ldap.LDAPException: error resiult(65): Object class violation" And the messages file throws the error (/var/log/dirsrv/slapd-<instancename>/errors: "Entry "uid=test,ou=People,dc=int,dc=com" -- attribute "memberOf" not allowed [17/Feb/2016:11:22:58 -0700] memberof-plugin - memberof_postop_modify: failed to add dn (cn=testgroup,ou=Groups,dc=int,dc=com) to target. Error (65)" So it seems my server isn't quite using the memberOf plugin properly, but I'm not sure what else to enable. I'll have to solve this issue before I even try to filter login access via groups on my client system. I should mention that if I go under the advanced tab for one of the groups I created, I can add the the attribute "uniquemember", but I'm not sure what I should set the "value" to be. I've tried creating new users to see if I could set their "uniquemember" attributes, but no luck. It seems that I don't have the ability to set this attribute on individual users, only groups. This might not be the right road to head down when trying to restrict access to servers via groups, so I'm open to any suggestions. Any suggestions would be appreciated.

tls encryption and key changes: symmetric key failed to unwrap
by Jan Kowalsky 04 Feb '19

04 Feb '19

Hi all, we have the following situation: An 389ds with tls/ssl configured whith an certificate from letsencrypt. Since letsencrypt is short-dated we have an automated update routine for regenerating the cert8.db. Now we have this sort of errors in changelog. [01/Jun/2018:11:46:40 +0200] attrcrypt - attrcrypt_unwrap_key: failed to unwrap key for cipher AES [01/Jun/2018:11:46:40 +0200] attrcrypt - attrcrypt_cipher_init: symmetric key failed to unwrap with the private key; Cert might have been renewed since the key is wrapped. To recover the encrypted contents, keep the wrapped symmetric key value. [01/Jun/2018:11:46:40 +0200] attrcrypt - attrcrypt_unwrap_key: failed to unwrap key for cipher 3DES [01/Jun/2018:11:46:40 +0200] attrcrypt - attrcrypt_cipher_init: symmetric key failed to unwrap with the private key; Cert might have been renewed since the key is wrapped. To recover the encrypted contents, keep the wrapped symmetric key value. [01/Jun/2018:11:46:40 +0200] attrcrypt - All prepared ciphers are not available. Please disable attribute encryption. I never used attribute encryption and we don't need it at the moment. But as far as I understand, it's based on the server private key. This is the one we change every 60 days. The best idea seems to disable attribute encryption (which doesn't make much sense if the private key isn't password protected anyway). Or is there any other way to deal with key changes? Thanks and regards Jan

error moving an user

Hey Guys, 389 version: 389-Directory/1.3.7.4.20170912git26a9426 B2017.255.1330 I'm trying to move one of my users to another OU and I see this kind of error: Error while moving entry - [LDAP: error code 1 - Operations Error] java.lang.Exception: [LDAP: error code 1 - Operations Error] at In the log I see: [20/Mar/2018:14:12:27.172553808 -0300] - ERR - ldbm_back_modrdn - SLAPI_PLUGIN_BE_TXN_POST_MODRDN_FN plugin returned error but did not set SLAPI_RESULT_CODE I thought that was related to my windows replication, but I disabled it and I'm still getting the error. Any clues?

More meaningful failure messages when changing passwords
by Mitch Patenaude 11 Jul '18

11 Jul '18

Our organization’s security policies impose several constraints on password changes. There is a complexity requirement, and a ban on reuse of old passwords. I’ve gotten all of these requirements worked into the 389 server, but when the constraints aren’t met, the error message is very misleading and opaque: Password change failed. Server message: Failed to update password passwd: Authentication token is no longer valid; new one required This results in a lot of support requests about the inability to change passwords. Is there any way to make the error messages a little more descriptive? We’re using pam_sss and sssd on Centos 7.x. Thanks, -- Mitch

Problems with 389-ds-base-1.3.7.5-24.el7_5.x86_64 on EL7
by Orion Poplawski 28 Jun '18

28 Jun '18

After our EL7 IPA servers updated to 389-ds-base-1.3.7.5-24.el7_5.x86_64 yesterday, we saw ns-slapd eventually start consuming 100% cpu, eventually failing to serve some requests, and eventually running out of file descriptors. I've filed https://pagure.io/389-ds-base/issue/49815 You may want to proceed cautiously with this update. YMMV. -- Orion Poplawski Manager of NWRA Technical Systems 720-772-5637 NWRA, Boulder/CoRA Office FAX: 303-415-9702 3380 Mitchell Lane orion(a)nwra.com Boulder, CO 80301 https://www.nwra.com/

tunning DS for idle timeout exceeded
by Ghiurea, Isabella 27 Jun '18

27 Jun '18

Hi List we are running 389-ds-base-1.3.5.15-1.fc24.x86_64 ( OS -FC24) analyzing access log file today , I am seeing for each of the client T1 msg, our applications are using www pools connection to ldap we have a large number of hosts cfg for min and max pools size , most of connections are always in a open/idle state to be reused by the client. Initial I had nssldap-idletimeout set to 120 sec, but today I went and increase by factor of 2 in hope to eliminate this T1 msg but no luck so far , the number of file descriptor is set to 4096. Here is one sample from access log output, I 'm looking to get some input how to tune DS to eliminate T1 message Client 6:...... 88 - Connections 84 - T1 (Idle Timeout Exceeded) [7] Client: 87 - Connections 84 - T1 (Idle Timeout Exceeded) [8] Client: 74 - Connections 70 - T1 (Idle Timeout Exceeded) Thank you

Re: Master-slave replication procedure
by Thomas E Lackey 24 Jun '18

By happy timing, we (Bozeman Pass) just added one of our in-house tools for configuring replication to GitHub: https://github.com/bozemanpass/replform. We call it `replform` as a slight nod towards Hashicorp Terraform. Obviously they are very different beasts, but what they have in common is that you specify the infrastructure / topology that you want, and the tool figures out what changes need to be made to make it happen (eg, create replication accounts, replica entries, changelogs, agreements, initialize the replicas, etc.) Running `replform plan` will tell you what it intends to do and `replform apply` will make it happen. It is safe to run over again, can handle adding new hosts, etc. It sounds like it might work for your case. There is more documentation and a few examples at: https://github.com/bozemanpass/replform -- Thomas E Lackey P.S. Some additional notes and warnings: It supports build MMR or supplier/consumer replication topologies (or some mix of the two), but not "chaining" replication with hubs. The other is that while it handles the removal of a consumer automatically, it does not do the RUV cleaning necessary when removing a supplier. Lastly, `replform` also supports pulling credentials for 'cn=repman' and 'cn=Directory Manager' out of Hashicorp Vault, but that require some Vault tools we created that haven't made their way into GitHub yet (though they likely will).
