Cannot confirm uidNumber 1001 is free: checking for the next on
by Juan Diego Calle 25 Oct '11

25 Oct '11

Hi, I have an issue with openldap and smbldap-tools. Maybe I am wrong, and it has nothing to do with openldap. At first I notice that for some reason when I was trying to create users with phpldapadmin all my users had the same ID, 1001, so I tried to create users with smbldap-useradd and found the following warnings: I know Cannot confirm uidNumber 1001 is free: checking for the next on .... Cannot confirm uidNumber 2670 is free: checking for the next on So after hours of looking at the code in php of phpldapadmin, and looking to i think it doesn't find the right number, for some weird reason in my configuration. It seems like this problems are related since for some reason the UID of the users is not easy to confirm. Could it be that I added the ids from my backup and some posix accounts users already had those ids and since then the rest of my UID got screwed. Has anyone had any similar problem in the past. Thanks

SLAPI plugins do not load
by Dimitri 24 Oct '11

24 Oct '11

Hi, Seems like loading SLAPI plugins is broken. I tried to play with addrdnvalues.c from the distribution, compiled it like it was recommended in the README: gcc -shared -I../../../include -Wall -g -o libaddrdnvalues-plugin.so addrdnvalues.c and tried to load from slapd.conf: plugin preoperation /usr/local/lib/libaddrdnvalues-plugin.so addrdnvalues_preop_init Here is what I've got running slapd: ================================================================================ [root@localhost ~]# /usr/local/libexec/slapd -u ldap -g ldap -d stats -f /etc/openldap/slapd.conf 4e9e21b0 @(#) $OpenLDAP: slapd 2.X (Oct 19 2011 02:18:15) $ mitya@localhost.localdomain:/usr/local/libexec/slapd failed to load plugin /usr/local/lib/libaddrdnvalues-plugin.so: file not found 4e9e21b0 slapd stopped. 4e9e21b0 connections_destroy: nothing to destroy. ================================================================================ The file /usr/local/lib/libaddrdnvalues-plugin.so exists and is readable; strace shows that it is in fact being opened successfully. Putting it into /usr/lib, /usr/lib/openldap and other locations does not help. This "file not found" message in fact is a well-known libltdl issue: lt_dlerror() reports "file not found" in any case of unsuccessful library loading attempt, including missing dependencies and unresolved symbols. Libtoolizing this plugin and supplying a .la file instead of .so does not help either. I am running current git master under Mandriva 2010.2 with libtool 2.2.6b, tried libtool 2.4 with the same result. Linking the plugin with explicit -lldap -lslapi (to satisfy potentially unresolved symbols) does not help. libslapi.so is in the library path. Statically linked slapd (with slapi_, ldap_ and ber_ functions) works the same way. Any suggestions? Dimitri

Need filter that allows members of specific group to authenticate, not sure how to build it
by Josh Cole 24 Oct '11

24 Oct '11

I am attempting to configure OpenVPN to use openldap to authenticate our Active Directory users who are a member of our VPN group in AD. Here is my ldap config for OpenVPN. Specifically I need the filter string to allow enabled users who are a member of the _VPN group. The one you see below is from an example script I found that explains how to configure LDAP for openvpn. SearchFilter "(&(objectClass=mailUser)(accountStatus=active)(enabledService=vpn))" Any help is appreciated! <LDAP> # LDAP server URL URL ldap://172.16.1.70 # Bind DN (If your LDAP server doesn't support anonymous binds) BindDN CN=ldapusername,OU=LDAP,DC=example,DC=local # Bind Password cn=vmail password Password ******* # Network timeout (in seconds) Timeout 15 </LDAP> <Authorization> # Base DN BaseDN "dc=example,dc=local" # User Search Filter SearchFilter "(&(objectClass=mailUser)(accountStatus=active)(enabledService=vpn))" # Require Group Membership RequireGroup false </Authorization> Josh Cole Network and Systems Engineer Fresno Pacific University (559) 453-3414

Can I use LDAP_VALID within my app/library?
by Khaled Blah 24 Oct '11

24 Oct '11

Hello to all, I would like to ask whether there is a way which allows me to use the macro "LDAP_VALID" in my own code. I would like to be able to check an LDAP* handle for its validity before I use that handle on any of the LDAP operation functions. Regards, Khaled

Overlays : Cache - Entry - AttributeDescription
by Johan Jakus 21 Oct '11

21 Oct '11

Hi everyone, I’m still working on my overlay for an OpenLDAP server, and I’ve a few questions, I hope you could help me with: 1. In my overlay, I search for the attribute of a parent (recursively) and then, I return it in the response using the “attr_merge” function as used in the “content” overlay. But, this seems to be a permanent change, the server will always return that attribute, till I restart the server. It’s like if the “attr_merge” function add the attribute in some kind of cache that is only cleared when the server shuts down. I ‘would like my attribute to be return only when I ask it, is there some other function that allow this or maybe a way to clear that cache? 2. I need to free some variables at the end of the request. It seems that the server goes through the response function one last time at the end of the request with an empty entry, I used that condition to free my variable. This seems to work perfectly, but is there may be another way to do that? 3. To determine what attribute I need to look up for parent’s attributes, I use a symbol before the attribute in the search request (ex: “_street”). This means that when the attribute arrives in the search function, it has no attribute description because the attribute name isn’t valid of course! So, I change the name, save the attribute name for later use and then use the “slap_str2ad” function do add the attribute description! But this means that the server as to go look for that attribute description again and this means decreasing the performance. My question is: Is there a way to change and saved the attribute name before the server loads the attribute descriptions and calls the search function? Since I’ve found a workarounds for question 2 and 3, question 1 is my biggest problem to make my overlay work properly! Thanks for your coming answers! Johan Jakus
