LDAP Groupfilter with range - active-directory

i have the following Groupfilter:
(name=*)(member;range=0-1)
The reason i use "range" is that i have groups in AD > 1500 users.
With the above testfilter i try to find the first two users.
If I use this filter, the result is always 0, I tried different filter variants, unfortunately without success.
If i just use (name=*), then i can find all the members.
Do someone have an idea, what could be wrong?
Thanks!

Your LDAP filter is not valid. When you have more than one condition, you need to add either an "and" (&) or "or" (|) operator.
But also, the "range" is not valid in the LDAP filter itself. It belongs in the list of attributes to return. How that's done exactly depends on which programming language you are using to make the query. If you show the rest of your code, I can help there.

Active Directory Query using LDAP Query in custom search

Some of the users in the domain I'm working on have no manager assigned or no Job title so I tried to create a new query with this LDAP query in the definequery>customsearch>advanced tab:
(&(objectCategory=user)(objectClass=user))(|(!manager=*)(!title=*)
This returns zero results even though I know they exist. Using the Custom Search creates the same search string and also returns zero results. I tried this, based on research elsewhere, which also returns zero results.
(&(objectCategory=person)(objectClass=user))(|(!manager=*)(!title=*)
What am I doing wrong?
Also I want to search only in specific folders and their subfolders, should I pre-pend this:
(|(OU=Innsbruck)(OU=Totnes)(OU=Dueren))
where these are immediately below the domain and each location has its own sub folders of Computers, Groups, Users.
Your query is just invalid. That window doesn't tell you that - it just gives zero results.
You're missing closing parentheses and you need to put the OR condition inside the AND condition. And you also need to use (objectCategory=person), not (objectCategory=user). You don't really need (objectCategory=person) since (objectClass=user) is good enough to limit the search to user objects, but it doesn't hurt.
This is what it should look like:
(&(objectCategory=person)(objectClass=user)(|(!manager=*)(!title=*)))
I will usually paste my query into Notepad++, which highlights matching parentheses, so it's easy to find missing ones. Or you can break it up over multiple lines to make it easier to read and easier to spot errors:
(&
(objectCategory=person)
(objectClass=user)
(|
(!manager=*)
(!title=*)
)
)
Regardless of how you search (through the Users and Computers UI or through code) you can only search one OU at a time. There is no OU attribute or any other attribute that you can use in a query to limit to specific OUs.
In the UI, you can click 'Browse' in the top right to pick the OU you want to search.
If you were doing this in code, you can do a couple things to limit it to specific OUs:
Search each OU separately (you can optionally set the Search Scope to not search sub-OUs if you want), or
Search the whole domain, then look at the distinguishedName attribute of each result and discard the results from OUs you don't want.
Option #2 will probably perform faster since it's less network requests.
It seems to me that the filter is not compliant with RFC 4515: LDAP String Representation of Search Filters.
May be AD and the tool you are using is accepting it, but NOT filters should be in the form of (!(manager=*)).
(&(objectCategory=person)(objectClass=user)(|(!(manager=*))(!(title=*))))

Use array formula with index match

Is it possible to do an array formula with index match:
e.g:
=arrayformula(if(len(A3:A),INDEX('SheetB'!E:E,MATCH(A3:A,'SheetB'!H:H,0))))
If not, is there a solution that doesn't involve google scripts?
It seems INDEX can not return multiple values. It can not be used inside ARRAYFORMULA.
The only solution I know of is to use VLOOKUP.
See this thread :
https://productforums.google.com/forum/#!topic/docs/jVvjbz8u7A8
Example from there :
=ArrayFormula(VLOOKUP( B12:B15; H2:R32; 1; TRUE))
Cheers!
Use XLOOKUP
=ARRAYFORMULA(XLOOKUP(K2:K,R2:R,S2:S))
With XLOOKUP you can look in one column for a search term, and return a result from the same row in another column, regardless of which side the return column is on
In the OP's specific case, one can actually use VLOOKUP for its intended purpose, as a replacement for MATCH:
=arrayformula(if(len(A3:A),VLOOKUP(A3:A,{SheetB!E:E,SheetB!H:H},2,false)))
In the general case of trying to use INDEX to retrieve multiple values, it can be replaced with a kludge of VLOOKUP and SEQUENCE:
=arrayformula(VLOOKUP(A:A,{SEQUENCE(rows(B:B)),B:B},2,true))
does what would have been accomplished by
=arrayformula(INDEX(B:B,A:A))
if the latter worked as OP expected.
I know this is old now, but it turns out that INDEX() acts as a defacto ARRAYFORMULA() now. You can see a fabulous example of this on this google sheet, which shows how to use a and index(split()) to extract a particular set of text from a cell. The MK.demo tab provides a visual on how the array formula is implied with the INDEX() function.
Nowadays, using a FILTER() or QUERY() function can give the kinds of multiple vlookup the OP was looking for.
im not sure if its gonna work but i did an "IF(ISBLANK() before the INDEX(...) in the ARRAYFORMULA and it went down all the way

ldap query syntax to exclude alpha characters

I'm trying to make adjustments to this LDAP query so that any employeeIDs that contain only numbers are included in the filter and anything else is skipped. (!employeeID=\00)will grab any ID that is not blank or null I believe, but how do I test for alpha or just numeric characters in AD? Thanks
-LdapFilter "(&(&(objectCategory=person)(objectClass=user)
(!userAccountControl:1.2.840.113556.1.4.803:=2))(&(objectCategory=person)(objectClass=user)
(!objectClass=inetOrgPerson))(sAMAccountName=s0*)(!sAMAccountName=*-d)(!sAMAccountName=*-e)
(!sAMAccountName=*-a)(!Name=Test*)(!Name=v-*)(!employeeID=\00))”
I don't think we can use the search filter to filter out non-digit values.
Found no related filters here:
http://msdn.microsoft.com/en-us/library/aa746475%28v=vs.85%29.aspx
Instead you may use a simpler filter to get all users, add those attributes (e.g. employeeID, sAMAccountName, etc.) to the properties-to-load list. And then filter that on client side.
Besides, filter like attr=*sth will be slow. The index only helps in equal (attr=sth) and start-with (attr=sth*) ones.

how can I make getaddrinfo return only one result?

I want to use getaddrinfo() but get only the first result.
more specifically, I want the function to first scan the hosts file and fetch the first result found, and only if not found in hosts I want to query the dns server.
is it possible?
thanks.
You can't. It behaves as documented. You only have to use one result: that's up to you.
The order on how resolving hosts is done is define in /etc/host.conf using the keyword order:
order
This keyword specifies how host lookups are to be performed.
It should be followed by one or more lookup methods, separated
by commas. Valid methods are bind, hosts, and nis.
However I doubt you can restrict the number of results to 1 per this configuration directly.

Dynamic Search multiple terms in linqtosql

I'm trying to do the following, If a user the enters the term "IP Address Text" into my search box then I want the following SQL to be generated:
SELECT *
FROM tblComments
WHERE tblComments.Text LIKE '%IP%' OR tblComments.Text LIKE '%Address%' OR tblComments.Text LIKE '%Text%'
Obviously the number of words entered is going to be different each time.
I have tried a for each loop in LinqToSql adding multiple where clauses but this uses "AND" instead of "OR"
Any idea how to accomplish this?
You may want to read up on full text searching as an alternative to what you're trying to accomplish here. Searching for '%word%' will never perform well as the query cannot use an index.
