I have a problem with the standard JNDI LDAP bind request and wanted to
know if OpenLdap behaves differently:
when creating and object with a LDAP addRequest with a context of
umObjectGUID=0, OU=People, DC=avaya
then I will automatically get a attribute: umObjectGUID with value "0".
So this is implicit, I do not specify this attribute. Unfortunately the
ldap server then responds that this attribute is readOnly.
Can anyone tell me if OpenLdap also add this implicit context
attribute, or perhaps what other options do I have here?
Thanks a lot,
In my openldap i created a OU called india
under this ou there are many users and one administrator as admin.
I want this admin user to add and modify the users details only in this ou.
for that i need to set the access control list.
Can any one plz help me how to set acl's for this case.
Remaining users have only read only permissions.
I have a group called IT and another one called LDAP Admins. There are
5 users under IT and 2 under LDAP Admins.
I'm looking for an acl where members of IT (groupOfUniqueNames) can
modify/write anywhere under ou=Users.... apart from those users under
the LDAP Admins group.
Can anyone give me a help about this please.
I've found only how to give access to IT group but not how to exclude
LDAP Admins (2 in total) where those 2 exist also under IT group.
Create an MX record in your DNS server with the IP of the server, to which you need to divert your mails to and then give the host's name in mailHost attribute of LDAP.

My plan is to use Kerberos and LDAP as a replacement for NIS.
My issue is that I need my kerberos credentials to map to a user in LDAP
so I can avoid permission issues when logging in with kerberos creds.
All the perms are based on the UNIX/LDAP users and groups. Thing is the
user id's are different between kerberos and LDAP.
The kerberos names consist of firstname_lastname@REALM. The ldap entries
are in the format of standard Unix user names or first letter of first
name and up to 7 characters of the last name (jmontana). I migrated the
LDAP entries from my existing NIS maps.
Now I understand that I can use SASL and authz-regexp in slapd.conf to
map these id's. Please correct me if I am wrong.
I added all the corresponding "krbName: first_last@REALM" to the users
when I added them to the LDAP directory.
For example for user Joe Montana..His ldap dn is "dn:
His uid is "uid: jmontana
And his Krb name is ""krbName: joe_montana(a)TEST.EXAMPLE.COM"
I think all the data is there to get a mapping I just am unsure of the
auth-regexp strings I need to add to the slapd.conf file.
Does anyone out there have any experience with this and better yet
provide the string or example of what strings I can use?
I have searched the net on how to authenticate with kerberos and
effictively login with a local id but have been unsuccessful in my
Appreciate any help.

I have 2 LDAP Servers (1 master and 1 slave) and I synchronize bdb database
by slurp daemon. So, when somebody needs to update his/her password or other
information, everything is done in master server and then slave server
receives this updates. This 2 servers are in the same physical place.
Now I am planning to put another LDAP slave in other geographical place (far
from this 2 servers) and because of that I am planning to put some slave
server receiving all updates from master server, but in all ldap client
machines in this new location I would like to configure this new slave
server (Slave server 2) as URI host in ldap.conf files. I mean
Location 1: Master server 1 and slave server 1
Location 2: Slave server 2
Is there any way to do:
1. ldap client machines in location 2 to authenticate using Slave server 2 ?
2. when client machines needs to change some ldap information (like password
or personal information), to force this update to occurs in slave server 2
and then master server 1 receives this uodate ?
Do I have to use 2 Master servers (1 in each location) ? If yes, can I
synchronize both BDB databases ? How ? Any other suggestions ?
Thanks in advance

I would like to know if it is possible to use the dynamic attributes
(obtained by dynlist overlay), in a ldapsearch query filter. I have
tried using it but it does not seem to be working. Is there any fix for
this or is there any other overlay which will allow me to perform an
operation similar to sql join across different DN?
Thanks and Regards,
Fantastic! What I was hoping/expecting to hear :-).

No. Some fortune 50s have every employee in an OpenLDAP Dynamic Group.

Community developed LDAP software.
I am looking into using OpenLDAP to manage users and groups for my
system. A single group may contain up to 50,000 users. Does the LDAP
group membership mechanism suffer any scalability problems at that size?
I've my own objectClass called 'Agency'.
It has fields called 'radius' and 'agencyName'.
I want to find out all 'agencyNames' such that 'radius' is less than 400.
How can I achieve this?
