I am trying to modify an item in LDAP using entryUUID.
ldapmodify --hostName localhost --port 1389 --bindDN "cn=Directory Manager" --bindPassword password <<+
dn: entryUUID=bf5e7357-90a6-4481-b464-4ed9e153fc44,dc=pm,dc=test,dc=com
changetype: modify
replace: Salary
Salary:100
+
If I use uid it works fine.
How we can use entryUUID to locate the item?
The LDAP ModifyRequest requires the Fully Distinguished Name of the LDAP Entry as described within RFC 4511.
You need to obtain the DN of the entry to make a modification.

We have a Google G suite with multiple domains and users with email addresses not always having the primary domain extension.
When ldap searching the Secure LDAP environment for a user with a non primary domain we get the wrong user DN back.
Example:
LDAPTLS_CERT=ldap-client.crt LDAPTLS_KEY=ldap-client.key ldapsearch -H ldaps://ldap.google.com -b dc=example,dc=com '(mail=user#company.nl)'
returns dn: uid=user,ou=Users,dc=example,dc=com
where it should return dn: uid=user,dc=company,dc=nl
But with this wrong DN the next step in my radius authentication (because that's where we are using this for) fails:
LDAPTLS_CERT=ldap-client.crt LDAPTLS_KEY=ldap-client.key ldapsearch -W -D uid=user,ou=Users,dc=example,dc=com -H ldaps://ldap.google.com -b dc=example,dc=com '(mail=user#company.nl)' with a
ldap_bind: Invalid credentials (49)
additional info: Incorrect password
which makes sense because LDAP cannot find the user.
whereas as binding with the right DN succeeds:
LDAPTLS_CERT=ldap-client.crt LDAPTLS_KEY=ldap-client.key ldapsearch -W -D uid=user,ou=Users,dc=company,dc=nl -H ldaps://ldap.google.com -b dc=example,dc=com '(mail=user#company.nl)'
If I query for the user with the corresponding base_dn from the user's email address the returned DN is ok, but I cannot dynamically adjust the based_dn depending on the users email address, I think, in freeradius
I’m not sure if this a problem of the google LDAP servers or a problem with the LDAP protocol or a problem with the way I/radius queries LDAP.
I'm thinking to implement scripting authentication in the authorize section and implement my own ldapsearch + bind , but I hope there's a better solution.
Thanks. Wessel
Try with ldaps://ldap.google.com:636.
We found unless the port is defined it does not work.
We also noticed that not all fields can be searched, i.e uidNumber.
I am new to working with LDAP, and my ultimate goal is to offer LDAP single sign-on in a web app. In order to achieve this, I'm trying to run ldapwhoami, but I'm running into issues. I am able to run other commands, like ldapsearch and ldapadd.
I'm running OpenLdap on Mac OS High Sierra.
My relevant slapd.conf looks like this:
access to *
by self write
by * read
by anonymous auth
database ldif
suffix "dc=test,dc=com"
directory openldap-data
rootdn "cn=admin,dc=test,dc=com"
## rootpw = secret
rootpw {SSHA}fFjKcZb4cfOAcwSjJer8nCGOEVRUnwCC
I then added a user with ldapadd -x -w secret -f shanson.ldif, where shanson.ldif looks like:
dn: cn=shanson,dc=test,dc=com
objectClass: inetOrgPerson
sn: Hanson
uid: shanson
cn: shanson
userPassword: secret
I am successfully able to search for and find this new user with ldapsearch -x "(cn=shanson)".
Now, I am trying to verify the user's credentials using ldapwhoami, and I keep getting an error:
> ldapwhoami -x -D cn=shanson,dc=test,dc=com -w secret
ldap_bind: Invalid credentials (49)
The same operation with my root admin user succeeds:
> ldapwhoami -x -D cn=admin,dc=test,dc=com -w secret
dn:cn=admin,dc=test,dc=com
I'm sure I'm just making a simple mistake or not understanding what I'm doing, but I don't really know where else to look right now for answers. Thanks!
It seems to have had something to do with the plain text password I set up. I installed Jxplorer and manually updated my user's password and hashed it with MD5, and now the ldapwhoami command works. If I set the password as plain text in JXplorer, ldapwhoami still does not work. Beyond that, I'm not entirely sure what I was doing wrong.
For me, my dn was wrong.
I did an ldapsearch with admin credentials to get the dn: uid=xxx,ou=xxx,dc=xxx,dc=xxx,dc=xxx
Then I did an ldapwhoami -x -D "uid=xxx,ou=xxx,dc=xxx,dc=xxx,dc=xxx" -w secret and it worked fine.
i have the following problem: i have installed and OpenLDAP server in which in the people/users tree the distinguished name have the following format:
Distinguished Name: cn=Luigi Rossi,ou=people,dc=prisma,dc=local
The problem is i wish to replace it using the uid (a.k.a. the account username) instead of the CN in order to have something like this
Distinguished Name: uid=lrossi,ou=people,dc=prisma,dc=local
I need this because i'm configuring ldap authentication for Alfresco Community 4.0.d and it need the username
ldap.authentication.userNameFormat=uid=%s,ou=people,dc=prisma,dc=local
Any help?
It's an old post but I ran into this myself. The answer was actually pretty simple. If you're using phpldapadmin to create accounts, you need to edit the posixAccount template. Look for the <rdn></rdn> tags. Replace the cn with uid and save. Your accounts will now be created with a DN in the "uid=%s,dc=example,dc=com" form instead of "cn=%s,dc=example,dc=com"
http://phpldapadmin.sourceforge.net/wiki/index.php/Templates#Template_Header_Configuration
Use the modify DN LDAP request (in this case using the legacy OpenLDAP ldapmodify tool):
The uid attribute may need to be added:
ldapmodify -h host -p port -D bind-dn -w password <<!
dn: cn=Luigi Rossi,ou=people,dc=prisma,dc=local
changetype: modify
add: uid
uid: lrossi
!
ldapmodify -h host -p port -D bind-dn -w password <<!
dn: cn=Luigi Rossi,ou=people,dc=prisma,dc=local
changetype: moddn
newrdn: uid=lrossi,ou=people,dc=prisma,dc=local
deleteoldrdn: 1
!

How to do this per object (not changing the format globally) in phpLDAPadmin:
click on the object in the hierarchy on the left to show up on the right
the title of the object is shown as: cn=Luigi Rossi
the subtitle just below contains "Distinguished Name: cn=Luigi Rossi,ou=people,dc=prisma,dc=local"
now click on "Rename" link just 4 lines below
change value "cn=Luigi Rossi" to "uid=lrossi"
that's it.
Worth mentioning is the ldapmodrdn tool, which e.g. in Debian is part of the ldap-utils package. It can read in a simple file where on first line is the old CN as a DN, and on the second line the new CN as an RDN. If there are many users to change, they can be all included in the same file, separated with empty lines.
With that tool its quite easy to process all the existing accounts and change their DNs.
I have an LDIF file that contains a bunch of test users.
I would like to change the password for some of these users and was wondering what would be the best way to do so.
Use ldapmodify with LDIF, for example:
ldapmodify -h hostname -p port -D dn -w password <<!
dn: uid=user,dc=example,dc=com
changetype: modify
replace: userPassword
userPassword: new-password
!
or specify a filename:
ldapmodify -c -a -f file.ldif -h hostname -p port -D dn -w password
Of course, use the correct attribute names, distinguished names, and so forth. The distinguished name used for the bind of the ldapmodify tool must have access rights to modify the password of the distinguished name specified in the LDIF.

LDAP: Using ldapmodify
In our corporate LDAP structure a 'user' has two attributes:
uid = the id of the user
manager = the DN of the user's manager
Since I'm writing a script to find out the organization chain for a user, I'd like to be able to find the uid of a manager with a single query. Right now, I have to do it in 2 queries:
$ ldapsearch -h ldap.example.com -p 389 -b dc=example,dc=com uid=myuid manager
dn: cn=mycn,L=AMER,DC=EXAMPLE,DC=COM
manager: cn=mymanagercn,L=AMER,DC=EXAMPLE,DC=COM
Parse out the cn value 'mymanagercn', then run another query:
$ ldapsearch -h ldap.example.com -p 389 -b dc=example,dc=com cn=mymanagercn uid
dn: cn=mymanagercn,L=AMER,DC=EXAMPLE,DC=COM
uid: mymanageruid
Is there a way to do this with 1 query? Bonus points if you can do this using the Net::LDAP Perl modules!
No. However, it should be possible with a properly designed API to accomplish this task in one connection, but not in one search request. If you are using the UnboundID Directory Server you can write a plugin using the Server SDK to alter the contents of the search result before it is returned to the client. The plugin could perform the search for the manager entry and append the results to the search result.
The second search can really be a lookup, as you have the complete DN. You shouldn't just strip out the CN, use the whole thing.
