remote credentials for local branch with authz-regexp
by Hugo Monteiro
Hello list,
I'm using translucent in a local server. That same server also has an
extra local database, which is a local only branch of the remote
database. This database is a subordinate and they glue together well.
Now, for the sake of management, i need to be able to identify to the
local database (rootdn) but using credentials from the remote database.
Assuming one has
translucent to remote - dc=example,dc=com
with remote admin user cn=admin,dc=example,dc=com
local - ou=localbranch,dc=example,dc=com
with rootdn admin user cn=admin,ou=localbranch,dc=example,dc=com
I tried the follwing on the local server
database hdb
suffix "ou=localbranch,dc=example,dc=com"
rootdn "cn=admin,ou=localbranch,dc=example,dc=com"
rootpw "secret"
directory "/var/lib/ldap/ou=localbranch,dc=example,dc=com"
index objectClass,sambaSID eq
lastmod on
authz-regexp
"cn=admin,dc=example,dc=com"
"cn=admin,ou=localbranch,dc=example,dc=com"
access to dn.base="ou=localbranch,dc=example,dc=com"
by * read
access to *
by dn="cn=admin,ou=localbranch,dc=example,dc=com" write
by dn="cn=admin,dc=example,dc=com" write
by * read
subordinate
The credentials used to connect to the remote server have full read only
access to the remote database.
So the problem is that when i try to authenticate using
cn=admin,dc=example,dc=com, to the local database branch, i can see the
bind request being transluced to the remote server without using the
authz-regexp map.
Any advice is appreciated,
Hugo Monteiro.

How can I check ldap is working well?
by Olivier PAVILLA
After upgrading my server (Lenny to Squeeze). Something happened.
/var/lib/ldap was empty. Thanku very debian installer :)
I made a new /var/lib/ldap/DB_CONFIG
I restarted ldap with something like this /etc/init.d/slapd start
I looked my syslog tail -f /var/log/syslog
and it contents that :
Feb 23 13:46:13 unverre slapd[4660]: slap_client_connect:
URI=ldaps://coruscan2.dumpsize.fr:636
DN="cn=replicapalpatine,ou=useraccess,dc=dumpsize,dc=fr"

Feb 23 14:06:14 unverre slapd[4660]: do_syncrepl: rid=008 rc 21 retrying
Anyone can translate this to me?

authzTo now X-ORDERED?
by Michael Ströder
HI!
I'm trying to configure proxy authz with 2.4.24 without luck testing with
ldapwhoami -X.
Now I wonder if attribute 'authzTo' is now handled as X-ORDERED [1].
Unfortunately the subschema subentry does not contain a attribute type
description for 'authzTo'. The server adds prefix "{0}" to my authzTo
attribute value.
Ciao, Michael.

Re: openldap problems authenticating
by Tim Dunphy
Hey guys
I took Quanah's advice and put the clear text password into
/etc/lapd.conf on the client.
I also noticed that the user account it was looking for was of a
posixAccount class. And I was missing the nis.shema. So I added
nis.schema to slapd.conf and restarted slapd and I was seeing the same
pattern. ldapsearches on the client were working just as they were
before and getents on the client were not. But I was seeing a new
error in the logs at this point:

Which from what I've googled means basically "object not found".

I am trying to search the directory using the pam_ldap account which
is an inetOrgPerson account and looks like this:

cn: pam_ldap
objectClass: top
objectClass: inetOrgPerson
sn: PAM
userPassword: {SSHA}Cbk8VNyWQsXNmqt6n9GYDRcR0cnuA2sJ
This command does find the bluethundr account:
ldapsearch -xH 'ldap://LBSD2.summitnjhome.com' -D
'cn=pam_ldap,ou=Services,dc=summitnjhome,dc=com' -w 'secret' -b
'dc=summitnjhome,dc=com' '(uid=bluethundr)'
(currently I'm not using TLS until I get this mess sorted out)
And I am using this /etc/ldap.conf on the client which as I've
mentioned is centos 5.5
host 192.168.1.44
base ou=staff,ou=Group,dc=summitnjhome,dc=com
sudoers_base ou=staff,ou=Group,dc=summitnjhome,dc=com
binddn cn=pam_ldap,ou=Services,dc=summitnjhome,dc=com
bindpw secret
scope sub
pam_password exop
nss_base_passwd ou=staff,dc=summitnjhome,dc=com
nss_base_shadow ou=staff,dc=summitnjhome,dc=com
I am definitely looking forward to an end to this vexing situation.
But once again let me state that I genuinely appreciate any time and
input you may be able to provide.

pam_ldap-1.8.5 A pam module for authenticating with LDAP
And this is what I am using on the Centos 5.5 client:
[root@LCENT01:~] #rpm -qa | grep -i ldap
python-ldap-2.2.0-2.1
openldap-2.3.43-12.el5_5.3

openldap-clients-2.3.43-12.el5_5.3
openldap-2.3.43-12.el5_5.3

Some advice is sorely needed here. Thank you very kindly in advance!

I've broken my installation
by Stuart Bailey
Hello,
I had a working openldap installation that I was developing some PHP to
manage. I'm using the ldap_bind PHP call without username & password, so it is
an anonymous bond.
I decided to have a clean install to verify everything was ok, so copied my
ldap config files, and reinstall on a clean system.
the problem is that now the anonymous bind will not work. I turned on all
debugging, and found the entry:
... do_bind: v3 anonymous bind
in the log. I'm guessing this means that anonymous bind is enabled, but still
my PHP code will not bind.
I'm not sure where to start to look for the problem.
Could someone please point me in the right direction. I can supply logs and
configs once I know where to look and what to send.
Many thanks,
Stuart

merging local and remote attributes
by Hugo Monteiro
Hello list,
I have been trying to use translucent overlay to merge attributes
between a remote and a local server (both 2.4.23).
From the slapo-translucent man page i read:
"Attributes may be specified as both local and remote if desired."
and
"In any case, both the local and remote entries corresponding to a
search result will be merged before being returned to the client."
The thing is that if i specify an attribute (objectclass) to be both
local and remote, i can only get/search for the local entries. Choosing
either separately will work as advertised though.
Again, i ask if this is a bug, a subtlety i have missed or this is not
supposed to work with objectClass attribute?
Please advise,
Hugo Monteiro.

Ipad/iPhone ldap setup
by Chris Jackson
I am having trouble accessing my openldap server over SSL using an iPhone/iPad/iPod Touch using ios 4.2.1. If I check the SSL box in the client setup on the iPhone/iPad/iPod Touch I get an error in the slapd log -- TLS negotiation Failure. With logging level 9 I get TLS accept failure error=-1 id=1.
Other clients work fine over SSL/StartTLS. Outlook, addressbook in osX 10.6, jxplorer.
I am using openldap 2.4.19-15 on RHEL6 with a comodo wildcard SSL cert.

Add GSSAPI to RootDSE ?
by Fabien COMBERNOUS
Hi the list,
I want to add a supportedSASLMechanisms in my rootDSE :
Today, i have all of this :
ldapsearch -LLL -b "" -s base -x '(objectclass=*)' supportedSASLMechanisms
dn:
supportedSASLMechanisms: NTLM
supportedSASLMechanisms: DIGEST-MD5
supportedSASLMechanisms: CRAM-MD5
I want to add GSSAPI. To add this i created the following ldif file :
cat /tmp/rootDSE
dn:
changetype: modify
add: supportedSASLMechanisms
supportedSASLMechanisms: GSSAPI
Then with simple autentication (-x) i used my testing olcRootDN to
modify the rootDSE :
ldapadd -f /tmp/rootDSE -x -D "cn=admin,dc=server,dc=lan" -W
Enter LDAP Password:
modifying entry ""
ldap_modify: Server is unwilling to perform (53)
additional info: modify upon the root DSE not supported
What i'm missing ?
