I'm trying to use ldapsearch to find the users who has their UID's from 0 - 4 characters in ldap.
eg:
mike
bike
like
ldapsearch "(uid>=4)" uid
But it doesn't give the response that way.

I am planning to create a cronjob that will change the password of my site every 15th day of the month. This is my .sh file
psql -U postgres -h (sample-host) (sample-db) -p (sample-port) -c "UPDATE web_user SET password_hash = '$2a$12$ohJ0j2Y9lRkO6Ld9MaiLuu7Q4hzYSr1IsM5SfY1SxAGk6fgn20aj2' WHERE email = 'email#email.com'"
When i run the query UPDATE web_user SET password_hash ='$2a$12$ohJ0j2Y9lRkO6Ld9MaiLuu7Q4hzYSr1IsM5SfY1SxAGk6fgn20aj2' WHERE email = 'email#email.com'; on pgadmin, everything is fine. The update is fine and the password is right. But when I run my .sh file on my machine(ubuntu 18.04), and even manually running it on the terminal, the result will be just a.
There are no errors messages or anything like that. Is there something that I missed? BTW the version of is postgresql 13.4.
Update: I just found out that special characters are causing the problem. it seems that the psql command does not allow special characters. The problem is I can't find any resources about these things.
For the special characters you need to a workaround
I tried in powershell, may be work in linux terminal
before:
postgres=# select * from web_user;
pass | email
------+-------
(0 rows)
used echo to output the password_hash as it contains special characters.
psql -U postgres -h localhost -d postgres -p 5432 -c "UPDATE web_user SET pass = '$(echo '$2a$12$ohJ0j2Y9lRkO6Ld9MaiLuu7Q4hzYSr1IsM5SfY1SxAGk6fgn20aj2')' WHERE email = 'email#email.com'"
output:
postgres=# select * from web_user;
pass | email
--------------------------------------------------------------+-----------------
$2a$12$ohJ0j2Y9lRkO6Ld9MaiLuu7Q4hzYSr1IsM5SfY1SxAGk6fgn20aj2 | email#email.com

I am totally new to LDAP, and have just started. I have seen a couple of examples, which to my understanding have used the query as I have done, but in my case it seems to be not working.
I have a hierarchy like this (I am using Apache Directory Studio):
If I double click on the object with ou=scientists then its info will pop up as followed:
So this group with ou=scientists has a cn=Scientists (I have checked and there are no following spaces after Scientists.
I want to simply find stuff inside the group with ou=scientists.
There is 1 way to do it like this:
ou=scientists,dc=example,dc=com which gives the expected result.
But I want to be able to find the content inside the group with ou=scientists not by its ou value, but by its cn value. So I thought to myself, ok I can use this: cn=Scientists,dc=example,dc=com
But this yields 0 results. I think I am missing a key point here. What should I actually do?
There are multiple things to consider when you query a LDAP directory.
In your case you want to lookup from a branch (call search base dn in LDAP) and apply a filter in all the childrens of this branch to select those you want :
ldapsearch ... -b <search base dn> -s sub "<FILTER>"
So for your DIT :
ldapsearch ... -b dc=example,dc=com -s sub "(&(objectClass=groupOfUniqueNames)(cn=scientists))"
Consider learning how the search request works in LDAP if you want to work more deeply with ldap : https://ldapwiki.com/wiki/SearchRequest
#SeanGoudarzi I think there is some misunderstanding about how LDAP model works.
If you want to find Sub-entries of a given entry, you need 2 searches.
One to find the base-entry and one to find the child entries
To find entry with so called 'relative distinguished name' ou=scientists you need a search like
ldapsearch ... -b dc=example,dc=com -s sub cn=scientists dn
and then
ldapsearch ... -b DN_RESULT_FORM_PREVIOUS_SEARCH -s one objectclass=* dn
this will give you
dn: ou=italians,ou=scientiests,dc=example,dc=com
Or do you want to achieve something else?
I wanted to search for mentioned entity from the ldapsearch:
ldapsearch -LLL -x -H ldaps://ldapserver -E pr=1000/noprompt -b "O=XXX,C=AN " "(dn=cn=firstName lastName 1231233,ou=employee,o=xxx,c=an)"
I get the output as
# pagedresults: cookie=
But when i search the same entity with its alias name, I am getting the whole object return from the command.
So, why I am not getting the return from the mentioned command.
I wanted to do the filter on the dn field from the as already mentioned and the same dn I got from the alias search field. So ideally I should get the result if I used the correct way to filter.
Please let me know if I made any mistake on the filter query.
You can access the entry by its dn using the following (probably what #user207421 suggested) :
ldapsearch -LLL -x -H ldaps://ldapserver -b "cn=firstName lastName 1231233,ou=employee,o=xxx,c=an" -s base
The key is to set the searched entry as the base with the appropriate scope, that is base.
I am currently working with LDAP which is on a UNIX server. The main purpose for me right now is to modify two entries in the directory by Ldapmodify through command line. The command is as follows:
ldapmodify -a -D 'cn=ldap,dc=cs,dc=ttu,dc=edu' \
-w *password* -H *server address* -f Documents/user.ldif
user.ldif file is as follows:
dn: cn=*username*,cn=Users,dc=ttu,dc=edu
changetype: modify
replace: displayName
displayName: abc
-
replace: loginShell
loginShell: /bin/tc
-
I get the following error when i try to run it:
ldapmodify: invalid format (line 5) entry: "cn=*username*,cn=Users,dc=ttu,dc=edu"
I checked the "dn" and it is correct. Why am I getting this error then?
I have a similar problem. In my case, my dn was correct, but it says "invalid format (line 16) ..." .
This is how I solved this:
The error msg can be misleading, because the dn is indeed correct. But line number "(line 5)" is an accurate pointer to the problem. In your case, I think the dash '-' is causing the problem. Try to remove the dashes and it may work!
is the cn RDN of the entry?
One can have an entry in directory sn=john, ou=Users .....
sn: john
cn: doe
displayName: johnny
the RDN is an attribute used as reference, in this case
dn: cn=doe,....
would be wrong, no matter that the entry has an attribute in specified value.
In the example you provided, DN is first line, and error says about 5th line.
Assuming you put it in some batch, maybe SOME entry has some special character in it's CN ?
And "Users" is usually an "ou" or "dc" or something, even if the container has "cn" attribute with "Users" as one of cn values. Are entries separated by empty newlines? Didn't you put minus sign after last modification of previous entry above, instead of one ( or more ) newline(s) ?
Oh, and when putting ldif with many entries ( changes ), it's wise to try it with "-n". And (actually for some reason I don't remember) I personally prefer to pipe ldif instead of "-f"
cat user.ldif | ldapmodify ...opts...
?
PS. haha :) try to remove "-a", it turns ldapmodify to ldapadd actually :) And add "-x" if you want to use "simple" auth ( with -w password ).
It must be the problem of character encoding of dash(-)
I met the same problem before because I edited file on windows and used it on centOS in Virtualbox
Then I made a new file in centos using touch and edited it using vi and it works.
I've ran into the same issue. In my case, I had an extra space after the dash (-) character separating the entries.
For example, note the space after the dash on line 5:
$cat -A sample.ldif
dn: uid=noelp,ou=People,dc=example,dc=co,dc=us$
changetype: modify$
replace: employeeType$
employeeType: fulltime$
- $
replace: title$
title: Sr IT Analyst$
-$
replace: employeeNumber$
employeeNumber: 1299$
Same issue can happen with a blank line with a space afer it.
I have one attribute (groupIDNumber), I want to make it work as auto-increment number?
How can we define that attr?
Thank for your help,

This blog suggests that you can achieve the equivalent by creating a new object that is sort of a sequence. A working implementation in OpenLDAP is reported here. The object is defined as follows (note: not my code, just reproducing what was reported):
----------------------------------------------
objectClass ( 1.3.6.1.4.1.4203.666.599
NAME 'uidNext'
SUP top STRUCTURAL
MUST ( cn $ uidNumber ) )
----------------------------------------------
LDIF entiries are then written as:
--- increment.ldif -------------------------------
dn: cn=uidNext,dc=example,dc=com
changetype: modify
increment:uidNumber
uidNumber: 1
-
---- EOF ------------------------------------------
And called with:
$ ldapadd -x -D "cn=Admin,dc=example,dc=com" -wsecret -f ./autoinc.ldif
This is not part of the LDAP protocol, nor is it a standard thing to do. It is something you would normally do in your client-side logic. However, depending on which LDAP server you are using, it may be possible to achieve using a plugin or extension.
