The log from samba says ldap: where's your test command says ldaps: maybe try ldap: from test command in case you only listen for ssl?

defining own attributes/class
by Zdenek Styblik 27 Oct '09

27 Oct '09

Hello, I would like to ask, if somebody knows a really good how-to about $subj. I've read couple books, let's say I'm able to define my own attribute, even extend some existing object - I think these are no problem, as they are based on trying right-wrong. My biggest concern is about numbering [OID/PEN ?]. I've requested PEN from IANA, no problem here. But how should I divide numbers to attributes? Does it matter? Can I run out of space? Do something [utterly] wrong? I just haven't seen this [numbering] explained to the last bit anywhere. Or may be, I've just read wrong. I mean, should it be like tree structure and eg. class1 = prefix.PEN.1.X; class2 = prefix.PEN.2.X; ...; classN = prefix.PEN.N.X; ? But may be there is no "bigger" sense I'm looking for and incremental numbering (+1 per attribute) is just enough. PS: for example, I would like to add JID [jabber ID]/IM [which would hold whatever Instant Messaging string] attribute and extend InetOrgPerson with this attribute. Thanks in advance for explanation/pointing me to the right direction.

Making copies of attribute values
by Ravi Verma 27 Oct '09

27 Oct '09

Dear Friends, I have a need to extend an LDAP schema by adding an attribute and copy the value from an existing attribute to it. We need to keep the two copies of the attribute values in synch. It is a kind of replication where it is replicating one attribute into another in the same record. I appreciate your help. -- Kind regards.

ppolicy and Red Hat Linux
by Joe Friedeggs 26 Oct '09

26 Oct '09

I need help/advise on ppolicy against Linux servers. I am running OpenLDAP 2.3.43-3.el5 (Red Hat rpm) on RHEL5. I am using the ppolicy overlay. The overlay seems to work to all of the tools, etc., that use this LDAP, except for the Linux servers. With these servers, we get no expiry warning, and users can log in after the password has expired (unlimited). We are using PAM/LDAP on these servers. Debugging this issue has caused me a bit of confusion. In the LDAP logs, when logging into other equipment that 'binds as user', I see warnings, etc. returned: ppolicy_bind: Setting warning for password expiry for uid=test_user,ou=people,o=theorg,dc=example,dc=net = 1251 secds BUT, since the Linux LDAP client has a separate 'binddn', I don't see these warnings when the Linux LDAP client does the ldapsearch to validate the user. How does the policy work in this situation? Am I missing something here? Here's what I see when I log in as a users (second login, pwdGraceAuthNLimit=2): login as: test_user test_user@linux_box's password: Last login: Fri Oct 23 19:39:03 2009 from 10.50.1.135 [test_user@linux_box ~]$ [test_user@linux_box ~]$ ldapwhoami -x -D "uid=test_user,ou=people,o=theorg,dc=example,dc=net" -W -e ppolicy Enter LDAP Password: ldap_bind: Success (0) (Password expired, 1 grace logins remain) dn:uid=test_user,ou=people,o=theorg,dc=example,dc=net Result: Success (0) [test_user@linux_box ~]$ [test_user@linux_box ~]$exit Then on the next login: login as: test_user test_user@linux_box's password: Last login: Fri Oct 23 19:39:26 2009 from 10.50.1.135 [test_user@linux_box ~]$ [test_user@linux_box ~]$ ldapwhoami -x -D "uid=test_user,ou=people,o=theorg,dc=example,dc=net" -W -e ppolicy Enter LDAP Password: ldap_bind: Invalid credentials (49);

Using Arbitrary X509 certificates for LDAPS authentication
by Stephen Cartwright 24 Oct '09

24 Oct '09

Hi there, Are there any restrictions on the DN or other attributes of credentials used for LDAP authentication? We are using grid credentials (X509 format) with DNs like this: issuer= /C=CA/O=Grid/CN=Grid Canada Certificate Authority subject= /C=CA/O=Grid/CN=host/somehost.somedomain.ca When I use some grid certs (X509 format) I see this message in the debug output from slapd: connection_read(10): unable to get TLS client DN error=49 id=3 When I try to connect, I get this: ldap_initialize( ldaps://somehost.somedomain.ca ) ldap_bind: Can't contact LDAP server The openssl command to create a connection works OK: CONNECTED(00000003) --- Certificate chain 0 s:/C=CA/O=Grid/CN=host/somehost.somedomain.ca i:/C=CA/O=Grid/CN=Grid Canada Certificate Authority 1 s:/C=CA/O=Grid/CN=Grid Canada Certificate Authority i:/C=CA/O=Grid/CN=Grid Canada Certificate Authority --- Server certificate -----BEGIN CERTIFICATE----- ... -----END CERTIFICATE----- subject=/C=CA/O=Grid/CN=host/somehost.somedomain.ca issuer=/C=CA/O=Grid/CN=Grid Canada Certificate Authority --- No client certificate CA names sent --- SSL handshake has read 2083 bytes and written 320 bytes --- New, TLSv1/SSLv3, Cipher is DES-CBC3-SHA Server public key is 1024 bit SSL-Session: Protocol : TLSv1 Cipher : DES-CBC3-SHA Session-ID: 43B46528E848663E7C8E9CAAEA4E6DB5E4A9675C05C3066DBD826CD1CF59A566 Session-ID-ctx: Master-Key: A8245A0731BA98F0D88821346432868C392FEE3F23EAFB9F356A34CB6BB663FC0892374118F280D6284C8E2ACAC3 Key-Arg : None Start Time: 1251330160 Timeout : 300 (sec) Verify return code: 0 (ok) When I use certs created by us with another DN format such as this: subject= /C=CA/ST=Province/L=Town/O=Organization/OU=Unit/CN=somehost.somedomain.ca/emailAddress=email(a)somewhere.ca issuer= /C=CA/ST=Province/O=Organization/OU=Town/CN=Our CA/emailAddress=email(a)somewhere.ca And then make no other changes to the config other than pointing everything to the new commands I can make a connection. Any suggestions? Please advise. Steve

ldapsearch vs AD output
by Cherubini Enrico 24 Oct '09

24 Oct '09

Good day, hope to be not OT. I have to get members of a group in AD, so here is what I do and what I get: ldapsearch -x -D "pippo(a)dominio.com" -w pippopw "cn=groupname" member:: W049X1MgVmlhPPAaXTDoCxPVT1fQSBNYW51dGOOOemlvbmUgZSBHZXN0aW9uZSBQYX= Rya W1vbmlvLERDPXByb3ZpbmNpYSxEQz12cixEQz1pdA=3D=3D member: CN=_SubGroup2,OU=_SubGroupArea,DC=dominio,DC=com If I do a search whith phpldapadmin I get both name (_SubGroup1 and _SubGroup2), so I guess the problem is how ldapsearch handles the output from AD server or in config file, but can't find a solution. Any hint ? TIA
