Another mod_shared_roster_ldap

I’m working on setting up an ejabberd server for our company for intranet communications. My goal is to setup rosters via your work of the mod_shared_roster_ldap. I’m not a computer technician, but a lonely pharmacist with some knowledge of linux and the inner workings thereof. I have compiled the latest version of the module and have it installed on my linux distribution (archlinux, not that matters too much). Ejabberd seems to be running fine, I can connect, add users, groups, and be authenticated via ldap, but the for the life of me I can get my rosters to work.

I have compiled the latest module from this link https://support.process-one.net/browse/EJAB-1480 and it seems to be running just fine. I just don't know where I'm going wrong with the config file.

So far I have the server seeing our all the domains in our forest so I know that the ldap connection is working. I’m having trouble sorting out what I need to put in the msrl portion of the config. Below is the setup so far.

{mod_shared_roster_ldap,[
{ldap_base, "dc=chs,dc=home"},
{ldap_rfilter, "(&(objectClass=user)(!(userAccountControl:1.2.840.113556.1.4.803:=2)))"},
{ldap_group_is_dn, "true"},
{ldap_gfilter, "(&(sAMAccountType=805306368)(!(objectClass=computer)))"},
{ldap_groupdesc, "ou"},
{ldap_memberattr, "sAMAccountName"},
{ldap_member_is_dn, "true"},
{ldap_member_selection_mode, memberattr_dn},
{ldap_ufilter, "(objectClass=user)"},
{ldap_useruid, "sAMAccountName"},
{ldap_userdesc, "displayName"},
{ldap_roster_cache_size, "0"}
]}.

A ldap search on an user via this command (ldapsearch -x -LLL -h chssvr02.chs.home -D "user@chs.home" -W -b "dc=CHS,dc=HOME" -s sub "(cn=user)" sends back the response (most of the private information has been removed).

As far as I can tell MSRL is finding users as on my ssh client it is scrolling through hundreds of usernames before stopping with this error.

Sorry to reply too late, but

Sorry to reply too late,

but the error seems to indicate some problem with LDAP itself.
The error name is invalidDNSyntax (invalid Distinguished Name syntax), I suspect some LDAP entity is internally malformed.
The error text is:

0000208F: NameErr: DSID-031001BA, problem 2006 (BAD_NAME), data 8350, best match of:
	'vicmau'

This seem to support my idea.
And so do your words that logs show normal operation until this "error" (that is not treated as error by ejabberd, as you may note, it's just =INFO REPORT====)

Hi Team, I have ejabberd

Hi Team,

I have ejabberd Server running with version 2.1.9.Also integrate into AD Server.
Right now i am using Chat JID as Mail attribute in AD server.

{ldap_uids, [{"mail", "%u@domain.com"}]}.

Could you please tell me how to use givenName and SN attribute in AD Server as like below

givenName.SN@domain.com

Please help to come out this issue.

Regards
Moorthy

ejabberd does not implement

ejabberd does not implement this. You only can use one attribute to construct jids.

Maybe there exist some possibility to create an intermediate LDAP server that would take data from AD and internally combine it to change the LDAP representation.

Hi, Thank you so Much. Is

Hi,

Is possible to Display the AD User Full Name in client using mod_shared_roster_ldap

Which module (and which

Which module (and which module version) do you use?
I mean, there are a original module from http://www.ejabberd.im/mod_shared_roster_ldap, improved module by porridge from https://alioth.debian.org/projects/ejabberd-msrl/, bundled version since 2.1.6 that was prepared by porridge, and an unofficial patch from https://support.process-one.net/browse/EJAB-1480. As you use ejabberd 2.1.9, it seems sensible that you should be using the bundled version, but the error seems to indicate a very old module, so maybe you have replaced the bundled version?

Hi mike, I am using

Hi mike,

I am using mod_shared_roster_ldap which is included in Ejabberd 2.1.9 package.

you want me to try with some other package?

Thanks

No, I would like you to copy your mod_shared_roster_ldap config here, please use copy/paste, not retyping, just don't forget to remove sensitive data. I suspect some typo in it.

Also Help me to sort Users in Group

Thanks Again

Very strange. I have hoped to find an error there - say, a missing letter. Everything looks OK.
Well then, you say that if you comment out the "ldap_filter" string, it works, but returns triple copies of every account. Could you post here a part of logs where the ldap queries are being made? As the log may be lengthy, you may wish to send it to me to mikekaganski@hotmail.com (or put it to a web share and post the link here, but note that this forum may put a message with URLs to moderation). Don't forget to purge sensitive info from there.

Also, please provide the client-server xmpp conversation regarding roster retrieval. You may need to use a client xmpp console (Miranda IM and pidgin have it).

Hi Mike I send the Details
