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

ShadowMax is not working
by cbulist 17 Sep '12

17 Sep '12

Hi, I have set a user with ShadowMax to 15 in order to get a expiration warning but it doesn't work and the client gets login. (I'm not using Password Policy) I read some post and them reference to pam_ldap.conf on the client, but I do not see any option about it. My openldap server version is: 2.4.23-26 Any clue with this problem? Thanks!

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

Need help on ACL
by Alexis GÜNST HORN 17 Sep '12

17 Sep '12

Hello to all, I need your help with OpenLDAP ACL. Here is my DIT : dc=example,dc=com ou=Users uid=user1 uid=user2 ou=Groups cn=... cn=... I use that to do Unix Auth with pam. It works fine. Now, i need to modify my tree like that : dc=example,dc=com ou=Users uid=user1 uid=user2 ou=Foo uid=user3 uid=user4 ou=Groups cn=... cn=... So, I've added the OU "foo" to "Ou=Users". In my network, all PCs are configured with pam_ldap reading "dc=example,dc=com". So, when i do : $ getent passwd I have : user1 user2 user3 user4 What I want : * if i'm "Ou=Users" member, for example "user1", with pam_ldap suffix : "dc=example,dc=com" : $ getent passwd user1 user2 * if i'm "Ou=Foo" member, for example "user_b", with pam_ldap suffix : "dc=example,dc=com" : $ getent passwd user3 user4 Is it possible to do so without modifying the DIT structure ? (only with ACL ?) Thanks a lot for your help. -- Alexis GÜNST HORN System administrator Exascale Computing Research

insert an olcAccess line in cn=config?
by Aaron Bennett 13 Sep '12

13 Sep '12

Hi, This might be more of an Apache Directory Studio question, so please forgive me... I'm using Apache Directory studio to edit cn=config and I have some lines like this: olcAccess: {0}to attrs=foo by <stuff> olcAccess: {1}to attrs=bar by <stuff> olcAccess: {2}to attrs=booboo <stuff> olcAccess: {3}to * by <stuff> read Order is important in these - so how do I add a value between {1} and {2}, for example? If I add olcAccess: to mailattr by <stuff> read then it goes in as oldAccess: {4} and as I understand ACLs it will never get it because the preceding * will match first, right? - Aaron --- Aaron Bennett Manager of Systems Administration Clark University ITS

Re: ACL entry creation restricted to objectClass

In order to restrict access to specific values of >the objectClass attribute you need to use the form >access to attrs=objectClass val=person ... >p. Many thanks for your answer. hmmm, so my usage of @<objectClass name> sound correct to me. Please have a look into my original example: I wanted to restrict newly created entry to be of class "person" only. Thus I restricted the attrs using @person, in the hope that account-specific attributes (uid, serialNumber) are denied. Nevertheless, the logs show that an account entry is created. The sample acl statement works as intended in case of a modify-operation (ldapmodify'ing a single attribute of an existsing entry). During creation the attr=entry seems to overwrite the oc-specific restriction or slapd cannot differ between differen objectclasses and/or attributes during entry creation (ldapadd)? If I'm wrong, could you please give me a short example acl set that denies the creation of account but grants creation of person entries? Thanks again!

slapindex with mdb
by Marco Schirrmeister 12 Sep '12

12 Sep '12

Hi, when I run slapindex with my mdb backend the data.mdb files grows and grows and when the configured maxsize (100GB) is reached it stops with cannot allocate memory. 50505d1e => mdb_idl_insert_keys: c_put id failed: Cannot allocate memory (12) 50505d1e => mdb_tool_entry_reindex: txn_aborted! err=80 To test, I created a very basic config. See below. Created a test ldif file with the LDIFGen.jar with 100000 DNs. The file is 110MB. In the slapd.conf is only 1 index configured. uid with eq,sub. When I load this file with slapadd the data.mdb file gets 268MB. (Without any configured index 220MB) When I then run a slapindex, the data.mdb grows to 20GB. If I add 2 more attributes to index. data.mdb gets 36GB index givenname eq,sub index sn eq,sub My question is, is this normal? Why does the data file get's so big with a slapindex and not with a slapadd?
