questions to differences between RFC2253 & RFC4514
by Peter Marschall 19 Sep '12

19 Sep '12

Hi, I am currently in the process of updating the DN parsing routines of perl-ldap and found some differences on border cases between RFC 2253 & RFC 4514 As you are more knowledgeable than I in LDAP (you wrote the specs ;-), could you please give me your opinion on the test cases below and whether my interpretations are correct. Thanks in advance for your help Peter <OU=Sales+CN=J. Smith;O=Widget Inc.;C=US> * illegal in RFC 4514 [I guess this is wrong;-] * in RFC 2253 [ { 'CN' => 'J.

Help with ACL to allow member of groupOfNames to read their entry
by Josh Miller 18 Sep '12

18 Sep '12

I am using OpenLDAP 2.4.23 on CentOS 6 and trying to setup ACLs to allow simpleSecurityObjects who are members of a groupOfNames to read their entry (but not write) and ideally not see other member attributes in that same groupOfNames. These simpleSecurityObjects exist in various OUs and reside in the same OU as the groupOfNames that they require access to. I'm using the memberOf overlay to maintain memberOf attributes within each simpleSecurityObject (which works well). Sample simpleSecurityObject and groupOfNames: uid=josh,ou=first string,dc=example,dc=com objectClass: account objectClass: simpleSecurityObject objectClass: top uid: josh dn: cn=group1,ou=first string,dc=example,dc=com objectClass: groupOfNames cn: group1 member: uid=josh,ou=first string,dc=example,dc=com Here is what I have so far for ACLs: dn: olcDatabase={1}bdb,cn=config changetype: modify add: olcAccess olcAccess: {0}to attrs=userPassword by anonymous auth by self write by group.exact="cn=ol-admins,ou=groups,dc=example,dc=com" write by * none - add: olcAccess olcAccess: {1}to dn.subtree="ou=power users,dc=example,dc=com" by anonymous auth by self write by group.exact="cn=ol-admins,ou=groups,dc=example,dc=com" write by dn.exact="uid=power users admin,ou=service accounts,dc=example,dc=com" write by dn.exact="uid=power users readonly,ou=service accounts,dc=example,dc=com" read by dn.exact="uid=global-ro,ou=service accounts,dc=example,dc=com" read by users search by * none - add: olcAccess olcAccess: {2}to dn.subtree="ou=third string,dc=example,dc=com" by self write by anonymous auth by group.exact="cn=ol-admins,ou=groups,dc=example,dc=com" write by dn.exact="uid=third string admin,ou=service accounts,dc=example,dc=com" write by dn.exact="uid=third string readonly,ou=service accounts,dc=example,dc=com" read by dn.exact="uid=global-ro,ou=service accounts,dc=example,dc=com" read by users search by * none - add: olcAccess olcAccess: {3}to dn.subtree="ou=second string,dc=example,dc=com" by self write by anonymous auth by group.exact="cn=ol-admins,ou=groups,dc=example,dc=com" write by dn.exact="uid=second string admin,ou=service accounts,dc=example,dc=com" write by dn.exact="uid=second string readonly,ou=service accounts,dc=example,dc=com" read by dn.exact="uid=global-ro,ou=service accounts,dc=example,dc=com" read by users search by * none - add: olcAccess olcAccess: {4}to dn.subtree="ou=first string,dc=example,dc=com" by self write by anonymous auth by group.exact="cn=ol-admins,ou=groups,dc=example,dc=com" write by dn.exact="uid=first string admin,ou=service accounts,dc=example,dc=com" write by dn.exact="uid=first string readonly,ou=service accounts,dc=example,dc=com" read by dn.exact="uid=global-ro,ou=service accounts,dc=example,dc=com" read by users search by * none - add: olcAccess olcAccess: {5}to dn.subtree="ou=fourth string,dc=example,dc=com" by self write by anonymous auth by group.exact="cn=ol-admins,ou=groups,dc=example,dc=com" write by dn.exact="uid=fourth string admin,ou=service accounts,dc=example,dc=com" write by dn.exact="uid=fourth string readonly,ou=service accounts,dc=example,dc=com" read by dn.exact="uid=global-ro,ou=service accounts,dc=example,dc=com" read by users search by * none - add: olcAccess olcAccess: {6}to * by self write by anonymous auth by group.exact="cn=ol-admins,ou=groups,dc=example,dc=com" write by dn.exact="uid=global-ro,ou=service accounts,dc=example,dc=com" read by dn.exact="uid=readonly,ou=people,dc=example,dc=com" read by * none I've tried placing the following ACL in various places in the list and it has failed to work each time: (re: http://www.openldap.org/doc/admin24/access-control.html) olcAccess: to attrs=member,entry by dnattr=member selfwrite by group.exact="cn=ol-admins,ou=groups,dc=example,dc=com" write by dn.exact="uid=global-ro,ou=service accounts,dc=example,dc=com" read by dn.exact="uid=readonly,ou=people,dc=example,dc=com" read by * none Any assistance would be greatly appreciated.

ldapadd long line problem
by Amol Kulkarni 18 Sep '12

18 Sep '12

Hi, I'm unable to add a long line (more than 4096 chars) in a field using ldapadd. I've openldap 2.4.30. I had 2.4.23 earlier and it used to work. So I tested again by keeping the slapd daemon of 2.4.30 but using ldapadd from 2.4.23. It works with the ldapadd from 2.4.23. Also it works in 2.4.30 if : 1. I reduce it to less than 4096. 2. I break down the long line into multiple lines. Has anyone come across this behaviour ? Is is something new added in the new version ? Thanks in advance, Amol.

Proxy setup not caching against Active Directory
by Xavier Garcia 17 Sep '12

17 Sep '12

Dear all, I am setting up a proxy to cache queries against Active Directory, so our Postfix servers do not hammer the AD servers. To do so I am using rwm and pcache with the following configuration: overlay rwm rwm-normalize-mapped-attrs yes rwm-map attribute uid sAMAccountName rwm-map attribute mail proxyAddresses rwm-map attribute maildrop smtp rwm-map attribute mailbox imap rwm-map attribute domain msExchAcceptedDomainName rwm-map attribute * tls ldaps tls_reqcert=never overlay pcache pcache bdb 10000 1 50 900 directory /var/lib/ldap/cache cachesize 10000 #index uid,mail,maildrop,mailbox eq index uid eq index mail eq # cache configuration proxyCacheQueries 10000 pcacheAttrset 0 uid mail maildrop mailbox pcacheTemplate (uid=) 0 900 pcacheTemplate (mail=smtp:) 0 900 When running: ldapsearch -x -LLL -E pr=200/noprompt -h 127.0.0.1 \ -D "CN=username,OU=users,DC=company,DC=com" \ -w "passsssworddddd" \ -b "OU=users,DC=company,DC=com" -s sub "(mail=smtp:me@company.com)" maildrop It never gets cached. query template of incoming query = (mail=) QUERY NOT ANSWERABLE QUERY NOT CACHEABLE I have read the pcache manual many times, but I cannot find the reason. Perhaps you can find the problem. Regards, Xavier Garcia

Message to Change Password
by Soporte Ti 17 Sep '12

17 Sep '12

Hi all, I have a question to pose, I inherited a FDS or dirsrv installation, which works without problems, but I have a single detail that I would like to ask and see if they can guide me (tell them that my experience is not much in openldap) When accounts are expiring starts giving a message like this: "Your password will expire LDAP in 2 days." the point is that the user changes the password but after that continues with the message, the password expiring after 2 days as indicated in message the question is, what is the command or statement that I use to change the password without this happening again? Best regards. Cristian
