LDAP Search Fails With Error «error code 4 — Sizelimit Exceeded»

Still need help?

The Atlassian Community is here for you.

Symptoms

There are two different cases where this issue can occur;

Symptom 1: Users aren’t able to login.

When integrated with SunONE LDAP Server, the following error is logged in atlassian-crowd.log file;

Symptom 2: Testing a Directory Connector fails!

Performing a test search in the Directory Connector Configuration tab fails with similar error.

Cause

Cause for Symptom 1 .

SunONE doesn’t support data paging

Cause for Symptom 2 .

This is a known bug which is fixed in Crowd 2.0.3. The fix works for Connector Directories only. The Delegated Directories may present the problem but it would not impact the normal directory functioning.

Resolution

Resolution for Cause 1 .

Set LDAP property search-size-limit to a higher value.

The value (the default being 2000) depends on the maximum number of elements (users, groups and roles) your Crowd server will have to fetch at once from the LDAP server.

Resolution for Cause 2 .

The bug is fixed in Crowd 2.0.3, if you are affected by this issue please upgrade to the latest Crowd version.

What if these don’t work?

Please have a look over this KB Unable to Log In with Confluence 3.5 or Later Due to ‘LDAP error code 4 — Sizelimit Exceeded’ which involves turning off paged results.

LDAP — javax.naming.SizeLimitExceededException

Your Elements Connect fields configured with an LDAP datasource fail with a similar error:

This error is returned by your LDAP server, that means the problem seems to be outside Jira actually. LDAP error codes are always explicit, in your case, here is the meaning:

LDAP: error code 4 — Sizelimit Exceeded:

LDAP Server settings. There isn’t a universal way of solving this problem, for it depends on a number of reasons: what kind of server you are working with, whom the server belongs to, whether or not you enjoy administrator rights and physical access to the server. If your server is absent in the list of solutions recommended for well-known servers, we suggest you ask your system administrator or consult the server documentation.

Workaround for well-known servers:

Microsoft Active Directory. By default, Microsoft Active Directory which is a part of Windows 2000 Server, allows fetching only 1000 entries per one search request. In terms of this system such a restriction is called MaxPageSize. This parameter can be changed using the ntdsutil.exe file which is a command line tool supplied with Windows 2000 Server. Another way to change this parameter is to edit it directly inside the CN=Default Query Policy, CN=Query-Policies, CN=Directory Service, CN=Windows NT, CN=Services, CN=Configuration, DC=YOUR_COMPANY, DC=YOUR_COMPANY_TLD entry by using LDAP Administrator. In both cases you must have administrator rights.

OpenLDAP. The time limit for the OpenLDAP server can be changed in the config file (which can usually be found at /etc/openldap/slapd.conf). The parameter is called sizelimit. For more information please consult the slapd.conf Manual page or the OpenLDAP documentation.

Resolution

This issue originates from the LDAP server, please contact your LDAP administrator.

javax.naming.SizeLimitExceededException: [LDAP: error code 4 — Sizelimit Exceeded]; #38

Comments

why set sizelimit to 1 ?

The text was updated successfully, but these errors were encountered:

Ideally — when you’re looking up a user in an LDAP tree, you should find a unique user matching the criteria specified. Otherwise, it’s ambiguous which user is attempting to login.

Can you explain why you think the sizelimit needs to be something else?

sorry for that, that my mistake, i think i found a bug , i have two username ,one is puqiaoming, this username can login, another is qiaoming ,when i login with qiaoming have error below:

Thanks for the bug report. @maheshp @bdpiparva — can one of you look into this?

@inits — Please can you provide what value you have used for user UserLoginFilter in your auth config?

is default below
(|(sAMAccountName= )(uid= )(cn= )(mail= )(otherMailbox= ))

@bdpiparva and @maheshp — should we use * around the filters (|(sAMAccountName=*<0>*)(uid=*<0>*)(cn=*<0>*)(mail=*<0>*)(otherMailbox=*<0>*)) . I’d think it should simply be (|(sAMAccountName=<0>)(uid=<0>)(cn=<0>)(mail=<0>)(otherMailbox=<0>))

@ketan — No we don’t need * around filters.

@inits — Please can you change it to (|(sAMAccountName=<0>)(uid=<0>)(cn=<0>)(mail=<0>)(otherMailbox=<0>)) . It should resolve your issue.

@bdpiparva — are you suggesting that we fix the default value in the plugin?

Yes, I am still looking for a way to validate username after searching user from LDAP tree.

But that filter is passed to the LDAP server itself, right? As long as there is no *<0>* , we shouldn’t need to validate anything. No?

@arvindsv —Yes, you are right but UserLoginFilter is the configurable field. At least validation to check filter contains * need to be there. right?

@ketan — #38 (comment) there is no default value for UserLoginFilter . Ignore what I said earlier.

@ketan — #38 (comment) there is no default value for UserLoginFilter. Ignore what I said earlier.

Is this just a documentation/tooltip/help-text fix then?

@arvindsv —Yes, you are right but UserLoginFilter is the configurable field. At least validation to check filter contains * need to be there. right?

I don’t know how you’d do that — unless you parse out the filter text into a syntax tree like thing. Is that even possible with the current implementation?

Perhaps this can be achieved by a simple warning in the plugin config that detects a *<0>* pattern?

Yes, that is what I am planning.

  1. Tooltip on the configuration page
  2. Detect if filter contains any *<0>* , * <0>, or <0>* then show error.

I wouldn’t show an error. Since it is user-configurable, we should allow them to configure it however they want. We can warn (or show a tooltip), but it should not stop them from setting that value. For all practical purposes, it should be opaque to GoCD.

The documentation definitely needs to change.

In places such as this as well.

@bdpiparva and I talked. Here are some notes:

In UserSearchFilter *<0>* is appropriate. This is so that «Add user» functionality and others such as that will work, and find users by partial name.

In UserLoginFilter *<0>* is not appropriate. It has the potential of finding mutiple users for a given username, when logging in. This is what is happening in the original exception.

None of our documentation needs to change, because we do have it correct. We will consider a warning in the tooltip message of UserLoginFilter warning against using *<0>* . Something like: It is not recommended to have *<0>* in this field as it can match other users.

We were able to reproduce this in a test and we will be showing a better exception message. In essence, we will be differentiating between a hard limit of 1 match during login and a soft limit of 10 or 15 matches for «Add user» functionality, which should take care of this problem. In one LDAP search base, if a user, while logging in, matches multiple LDAP records, then an error will be logged.
