How to bind a user and ensure they are in the correct group? - ldap

I think what I am trying to do is fairly simple, I want to setup ldap so that incoming binds check that the password is correct and the user is a member of a specific group.
Running the following query yields the following
ldapsearch -x -LLL -H ldap:/// -b uid=myname,ou=users,dc=example,dc=com dn memberof
Result
dn: uid=myname,ou=users,dc=example,dc=com
memberOf: cn=admin,ou=groups,dc=example,dc=com
I have tried the following query
ldapsearch -x -H "ldap://localhost" -D "(&(cn=My Name)(memberOf=cn=admin,ou=groups,dc=example,dc=com))" -W -b "dc=example,dc=com"
ldapsearch keeps throwing the following error
ldap_bind: Invalid DN syntax (34)
additional info: invalid DN
What am I doing wrong?

There are 2 things to fix in your search query :
the filter part should be placed after all options and before the list of attributes if any.
the -D option requires an argument, a bind dn to bind to the LDAP directory.
In other words : ldapsearch -x -H <ldapuri> -D <binddn> -W -b <basedn> <filter>
Assuming you can use this bind dn cn=manager,dc=example,dc=com, you should end up with a query looking like this :
ldapsearch -x -H "ldap://localhost" -D "cn=manager,dc=example,dc=com" -W -b "dc=example,dc=com" "(&(cn=My Name)(memberOf=cn=admin,ou=groups,dc=example,dc=com))"

Ldap query Trying to use group search and user search in same query but its not working,

ldapsearch -x -h <domain> -b "(&(cn=users,dc=apple,dc=com)(cn=groups,dc=apple,dc=com))" -s sub -LLL
Trying to use group search and user search in the same query but it's not working, suggest what is wrong or how it can be done.
I tried multiple query
ldapsearch -x -h nod.apple.com -b "(|(cn=users)(cn=groups))",dc=apple,dc=com -s sub
You can only make a search request to one base to a DSA (LDAP Server).
ldapsearch -x -LLL -h <domain> -b "dc=apple,dc=com" -s sub "(|(objectclass=group)(Objectclass=user"))
You can "Google/Bing" for ldapsearch examples or read https://www.openldap.org/software/man.cgi?query=ldapsearch

ldap_simple_bind: Invalid credentials

I'm trying a ldapsearch.
The user is "domain\user" and the connection and bind is successfull with ApacheDirectoryStudio (see image), however I don't understand how to use the -D parameter in ldapsearch (maybe the problem is the bachslash ?).
I've tried with:
ldapsearch -h IT.xxxx.COM -D "CN=domain\user,DC=it,DC=xxxx,DC=com" -w Password -b base 'objectClass=*'
but I get the error:
ldap_simple_bind: Invalid credentials --- 80090308: LdapErr:
DSID-0C090400, comment: AcceptSecurityContext error, data 52e
Thanks for help.

Apache-Connection
For connecting to AD over LDAP, you either specify the LDAP DN (e.g. CN=user,DC=domain) or the AD UPN (e.g. user#domain).
In your case, remove the domain from the LDAP DN:
ldapsearch -h IT.xxxx.COM -D "CN=user,DC=it,DC=xxxx,DC=com" -w Password -b base 'objectClass=*'
The domain is already represented by DC=it,DC=xxxx,DC=com.

Change passwords in an LDIF file using ldapmodify command

I have a LDIF file with a test user and I would like to change the password.
I used the ldapmodify command:
ldapmodify -h localhost -D uid=testuser,ou=users,dc=mytest,dc=org -w <password> <<!
dn: uid=testuser,ou=users,dc=mytest,dc=org
changetype: modify
replace: userPassword
userPassword: myNewPassword
!
modifying entry "uid=testuser,ou=users,dc=mytest,dc=org"
It's looks like working
But when I open my file.ldif, the password has don't change and ldapsearch command don't work.
ldapsearch -x -h localhost -D uid=testuser,ou=users,dc=mytest,dc=org -w myNewPassword -b uid=testuser,ou=users,dc=mytest,dc=org
ldap_bind: Invalid credentials (49)
Thank you for the help

ldapsearch with username and password

Here is my LDAP ORG Structure:
I created user with first, last name with password. But it is not working when am trying to connect using jdbc. Error says invalid credentials. Then I tried ldapsearch as follows:
I followed this process for users and group creation:
root#ip:/home# ldapwhoami
SASL/DIGEST-MD5 authentication started
Please enter your password:
ldap_sasl_interactive_bind_s: Invalid credentials (49)
additional info: SASL(-13): user not found: no secret in database
root#ip:/# ldapsearch -x -LLL -h ip -D username -w password -b"cn=admin,dc=ivhdev,dc=local" -s sub "(objectClass=*)" "givenName=username*"
ldap_bind: Invalid DN syntax (34)
additional info: invalid DN
Please suggest/correct me, if am passing the right info in DN syntax. I am unable to validate the user credentials with their name and password.
The -D option takes the DN for logging in to your LDAP server.
The -b option takes the search base in your LDAP tree where you want to search for the user's given name.
So, your ldapsearch command becomes:
ldapsearch -x -LLL -h ip -D 'cn=admin,dc=ivhdev,dc=local' -w password -b 'dc=users,dc=local' -s sub '(objectClass=*)' 'givenName=username*'
If you use the Apache Directory Studio (http://directory.apache.org/studio/) you can see the actual ldapsearch commands used by the application. Maybe this is useful for anyone.

Cannot wildcard search "member" in openLDAP

.
I have an odd problem, where I cannot seem to use wildcard searches for the "member" or the "uniquemember" attibutes for a group.
Consider the following:
cn=myusers,ou=groups,dc=example,dc=com
objectClass=groupOfNames
objectClass=top
This returns fine:
ldapsearch -h ldap-server -p 389 -D "cn=admin,dc=example,dc=com" -w Password -s sub -b "ou=groups,dc=example,dc=com" "(objectclass=groupOfNames)" member
cn=myusers,ou=groups,dc=example,dc=com
member=cn=user1234,ou=groups,dc=example,dc=com
And if I use this, it also works fine:
ldapsearch -h ldap-server -p 389 -D "cn=admin,dc=example,dc=com" -w Password -s sub -b "ou=groups,dc=example,dc=com" "(&(member=cn=user1234,ou=groups,dc=example,dc=com)(objectclass=groupOfNames)" member
But, suppose I want to find all the groups, with member names that start with "user". I try this:
ldapsearch -h ldap-server -p 389 -D "cn=admin,dc=example,dc=com" -w Password -s sub -b "ou=groups,dc=example,dc=com" "(&(member=cn=user*)(objectclass=groupOfNames))" member
But nothing returns!
Now I have tried adding indexes to the "member" and "uniquemember" attibutes as:
member pres,eq,approx,sub
uniquemember pres,eq,approx,sub
... but get a returned error of 'additional info: approx index of attribute "member" disallowed', so I was left with:
member pres,eq
uniquemember pres,eq
Even after the change, I still cannot perform wildcard searches using "member" or "uniquemember" attibutes. Any ideas?
.
This works as expected with the UnboundID Directory Server. Try updating the directory server software - there are some similar questions on the OpenLDAP forums where this problem was resolved by a fix to DN normalization.
Also, there is no such thing as a 'wildcard' search. The assertion value to which you refer results in what is called a 'substring' search. For increased performance, the server should index the member and uniqueMember attribute values for substring (sub), assuming the legacy OpenLDAP server supports indexing those attributes for substrings.
