NIS to ldap layout
by Eric Ritchie 24 Mar '08

24 Mar '08

I have 3 NIS domains I wish to convert to ldap. I would like to keep 3 separate areas in ldap since the NIS domains have different accounts. I created a base dn and loaded data under 3 higher levels, such as base is dc=xyz,dc=com and dc=a,dc=xyz,dc=com dc=b,dc=xyz,dc=com dc=c,dc=xyz,dc=com. Then if I want client one to be in domain a, I set its base to dc=a,dc=xyz,dc=com. This works for host name lookups but when another host tries to login to the box via telnet or rsh, the login hangs after the password is entered, ssh works though. If I specify a binddn on the client with dc=a,dc=xyz,dc=com, I can login via telnet and rsh but name lookups fail on the host. Any idea what is causing this? Is this the best way to have separate DBs for clients? Thanks -- Eric Ritchie Interactive Brokers LLC 203-618-5868

Authentication against translucent ldap server
by Javier Barroso 24 Mar '08

24 Mar '08

Hi, I've configured ldap translucent overlay with slapd-ldap as backend. Then I changed userPassword of a user. When I try to auth to the translucent server, the new password is not valid, and I have to introduce the password that be in ldap server which is being proxied. I would like new password would be the password used for auth. Do you know how could I configure such approach ? Thank you in advanced

Having troubles compiling openldap
by chris croswhite 21 Mar '08

21 Mar '08

Folks, There is probably an easy answer to this, however, I am stuck trying to compile openldap: getpeereid.c: In function 'lutil_getpeereid': getpeereid.c:64: error: storage size of 'peercred' isn't known make[2]: *** [getpeereid.o] Error 1 make[2]: Leaving directory `/var/tmp/openldap-2.4.8/libraries/liblutil' make[1]: *** [all-common] Error 1 make[1]: Leaving directory `/var/tmp/openldap-2.4.8/libraries' make: *** [all-common] Error 1 The struct type has its prototype in file sys/ucred.h but on linux (or at least all the variants I looked at), this is not a typical system file and google leads me to believe this is a BSD/BSD-variant system header. I am building with gcc4.3 and a linux w/2.4.25 kernel. Any clue what I am doing wrong here? Thanks!

Re: Numerical result out of range ... not solvable !
by Tamer Al-Khouli 21 Mar '08

21 Mar '08

But the entry exists in the openLDAP database and that's where it should check for it (since i configured pam to do do that). This is the whole point i am trying to get from centralized user authentication after all !! The openLDAP sever should be contacted to authenticate the users from different clients without the need for these clients to use their /etc/passwd files !

Numerical result out of range ... not solvable !
by Tamer Al-Khouli 21 Mar '08

21 Mar '08

Hi guys, I am setting up a centralized authentication server using openLDAP without TLS/SSL. I added the /etc/passwd and /etc/shadow entries, an looked them up using: $ldapsearch -x -D "uid=user1,ou=People,dc=example,dc=com" -w user1 "(objectclass=*)" where user1 is the password of the user user1, and i got all the entries. I also configured pam so that it uses pam_ldap. However, when i use the command su to switch to user1 ( which i commented out from /etc/passwd/) i get a message telling me that the user does not exist. Running slapd in the debugging mode i notice an errno=34 "Numerical result out of range". I googled it and found that this can be solved by adding the directives sockbuf_max_incoming and sockbuf_max_incoming_auth. I added the directives and tried with many values like 1234567, 999999, 9999999 for each of the them, still, i am getting the same error message. What else can i do to get rid of this error ?!

Ah, an interesting point, but probably a separate discussion. Note that the OpenLDAP memberOf overlay doesn't handle nested groups. > It's very clear that most of the time you have an identity and you want > to know what this Identity is part of, not the other way. No, not clear at all. A very common application of "groups" is for things like email lists. In that case, an MTA knows a specific group (the name of the email list), and needs to know all of the members. Other times (e.g. access control) you know an identity (current user) and want to know if the identity belongs to a particular group (for an authorization check). In that case, it is an equal amount of work to look in the user's entry for a memberOf value as to look in the group entry for the particular member value. In practice, because groups may be referenced frequently for multiple users, the group entries will be hot in the server cache and so the member lookup is actually cheaper. The frequency with which the question "what groups do I belong to" is asked is extremely low in most applications. The frequency with which the question "is XX a member of this group" is asked is very high in most applications. E.g., the libc initgroups() call needs to know what groups you belong to; that call typically occurs only once at the beginning of a login session. After that the result is essentially cached by the kernel. The result is cached in the kernel because the subsequent "is XX a member of group YY" questions happen so frequently as a process accesses system resources. > So you really want to do a single search on one entry, rather than a > huge search on the whole directory to find out (including local > calculation for nesting) what groups include that identity as member, by > parsing all groups one by one. > It is as simple as that. No, not simple at all. Yes, ideally you would like to be able to look in a single place and get the answer to "what privileges does user X have" but that doesn't actually mean what you're implying. In particular, the "single place" you're looking isn't necessarily that user's own entry. In most cases, that's the worst place to use because users generally have full write privileges to their own data, and the data comprising their set of privileges really belongs to the sysadmin, not to the individual user. Ideally, you write to the privilege set and read from the privilege set in the same way, in the same place. As an administrator, this simple consistency makes life easier. The memberOf concept is fundamentally broken if you actually rely on it for privilege determination because it is one step removed from how privileges are actually assigned by the sysadmin. (I.e., the sysadmin doesn't assign membership privileges to a user by writing to the memberOf attribute, therefore memberOf is not authoritative.) > Now for what concern the Samba4 problem, I think we should be more > creative and first understand in which cases we might hit a problem with > plugins like memberOf.

And frankly, there's already an existence proof that this approach is viable. -- -- Howard Chu Chief Architect, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/
