Hi, I am running Openldap-2.4.32, BD-5.3.21 and openssl-1.0.1c on RHEL 5.5. I created CA cert and singed it but when I run ldeapsearch with -ZZ I get the following error: TLS trace: SSL_connect:before/connect initialization TLS trace: SSL_connect:SSLv2/v3 write client hello A TLS trace: SSL_connect:SSLv3 read server hello A TLS certificate verification: depth: 1, err: 19, subject: /C=US/ST=Mass/O=Curry College/OU=Technology Center/CN=LDAP-SSL.curry.edu/emailAddress=adarouic@curry.edu, issuer: /C=US/ST=Mass/O=Curry College/OU=Technology Center/CN=LDAP-SSL.curry.edu/emailAddress=adarouic@curry.edu TLS certificate verification: Error, self signed certificate in certificate chain TLS trace: SSL3 alert write:fatal:unknown CA TLS trace: SSL_connect:error in SSLv3 read server certificate B TLS trace: SSL_connect:error in SSLv3 read server certificate B TLS: can't connect. ldap_perror ldap_start_tls: Connect error (-11) additional info: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed Please let me know if I missed something in my configuration.

Generated fields from static rules ?
by Yoann Gini 17 Oct '12

17 Oct '12

Hello, I’m new on this list. I actually try to configure a LDAP server to manage my identities (and use Kerberos as authentication backend). In my goal, I want to minimize information that need to be set by administrator to create entry. Here is a basic example : dn: uid=yoann,ou=people,dc=example,dc=com objectClass: inetOrgPerson objectClass: organizationalPerson objectClass: person objectClass: top objectClass: posixAccount cn: Yoann Gini gidNumber: 20 homeDirectory: /home/users/yoann sn: Gini uid: yoann uidNumber: 2000 givenName: Yoann loginShell: /usr/local/bin/zsh mail: yoann(a)example.com userPassword: {SASL}yoann(a)EXAMPLE.COM As you can see, they have many redundant informations… What I looking for is a way to fix some field for posixAccount or *,ou=people,dc=example,dc=com. For example, userPassword should be construct with a static text, a ldap entry and a global variable… {SASL}$uid$#KRB_REALM#. Like the mail : $uid$#domain# If you have any suggestion :-) Yoann

Nice tool! But how would I determine storage usage percent? ((Number of pages used)-(Free pages))/(Max pages)*100 or just (Number of pages used)/(Max pages)*100 ?

If I've failed to find this on the mailinglist or in my google searches, I am sorry. However, as I'm experimenting with using mdb for the backend with OpenLDAP-2.4.33 on RHEL 6.3, I'm wondering what am I looking for when I run mdb_stat and it tells me: Page size: 4096 Tree depth: 2 Branch pages: 1 Leaf pages: 2 Overflow pages: 0 Entries: 59 -- Frank Swasey | http://www.uvm.edu/~fcs Sr Systems Administrator | Always remember: You are UNIQUE, University of Vermont | just like everyone else.

Three issues with rwm overlay and olcExtraAttrs
by k3kk0n3n k3kk0n3n 16 Oct '12

16 Oct '12

[Resending this as the first one didn't seem to appear on the mailing list, I apologize if this creates a duplicate.] Hi, I believe I have found 3 issues related to the rwm overlay and the extra_attrs (or olcExtraAttrs) setting written to fix the issues described in ITS#6513 ( http://www.openldap.org/its/index.cgi/Software%20Bugs?id=6513;selectid=6513…). The description is long but I tried to provide as much information as possible. I am hoping someone can test and confirm the issues or tell me what I'm doing wrong if there in fact is no issue. I'm running version 2.4.32 on Ubuntu 10 and Debian Squeeze. 1) The documentation in the slapd-config manpage is incorrect. The olcExtraAttrs setting is said to be a global configuration setting when in reality it seems to be database specific. In the slapd.conf manpage, the corresponding setting (extra_attrs) is listed as being database-specific. I believe that is correct although I have not checked it. 2) olcExtraAttrs does not seem to work with the rwm overlay (like in ITS#6513). With the rwm overlay present, ACIs are not evaluated when requesting a specific attribute, regardless of whether olcExtraAttrs is specified or not. In order to apply the ACI, you can pass the ACI attribute name in the search. I'm providing a configuration file that can be used to reproduce the problem as well as some search examples to demonstrate the issue. ----Configuration file---- dn: cn=config objectClass: olcGlobal cn: config olcPidFile: /usr/local/var/run/slapd.pid olcArgsFile: /usr/local/var/run/slapd.args #olcLogLevel: -1 olcToolThreads: 1 dn: olcDatabase={-1}frontend,cn=config objectClass: olcDatabaseConfig objectClass: olcFrontendConfig olcDatabase: {-1}frontend olcAccess: {0}to * by dn.exact=gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth manage by * break olcAccess: {1}to dn.base="" by * read olcAccess: {2}to dn.base="cn=subschema" by * read olcRequires: authc dn: olcDatabase=config,cn=config objectClass: olcDatabaseConfig olcDatabase: config olcAccess: to * by dn.exact=gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth manage by * break dn: cn=schema,cn=config objectClass: olcSchemaConfig cn: schema include: file:///usr/local/etc/openldap/schema/core.ldif dn: cn=module,cn=config objectClass: olcModuleList cn: module olcModuleload: back_hdb olcModuleLoad: rwm dn: olcOverlay=rwm,olcDatabase={-1}frontend,cn=config objectClass: olcOverlayConfig objectClass: olcRwmConfig olcOverlay: rwm dn: olcDatabase={1}hdb,cn=config objectClass: olcDatabaseConfig objectClass: olcHdbConfig olcDatabase: hdb olcSuffix: dc=example,dc=com olcDbDirectory: /var/lib/ldap olcRootDN: cn=admin,dc=example,dc=com olcRootPW: pass olcDbConfig: set_cachesize 0 2097152 0 olcDbConfig: set_lk_max_objects 1500 olcDbConfig: set_lk_max_locks 1500 olcDbConfig: set_lk_max_lockers 1500 olcExtraAttrs: OpenLDAPaci olcAccess: to attrs=userpassword by anonymous auth olcAccess: to dn.base="dc=example,dc=com" by * search olcAccess: to * by self manage by dynacl/aci=OpenLDAPaci manage ----Note---- To disable the rwm overlay, comment the following 4 lines in the config: dn: olcOverlay=rwm,olcDatabase={-1}frontend,cn=config objectClass: olcOverlayConfig objectClass: olcRwmConfig olcOverlay: rwm ----Test data---- dn: dc=example,dc=com objectClass: dcObject objectClass: top objectClass: organization dc: example o: example dn: cn=a,dc=example,dc=com objectClass: top objectClass: person cn: a sn: a userPassword: pass dn: cn=b,dc=example,dc=com objectClass: top objectClass: person cn: b sn: b userPassword: pass OpenLDAPaci: 1#entry#grant;r,s,c;[all]#access-id#cn=a,dc=example,dc=com ----Search examples---- Without rwm, requesting the whole object (works as expected): ldapsearch -x -D cn=a,dc=example,dc=com -w pass -b cn=b,dc=example,dc=com # b, example.com dn: cn=b,dc=example,dc=com objectClass: top objectClass: person cn: b sn: b # numResponses: 2 # numEntries: 1 Without rwm, requesting an attribute (works as expected): ldapsearch -x -D cn=a,dc=example,dc=com -w pass -b cn=b,dc=example,dc=com sn # b, example.com dn: cn=b,dc=example,dc=com sn: b # numResponses: 2 # numEntries: 1 With rwm, requesting the whole object (works as expected): ldapsearch -x -D cn=a,dc=example,dc=com -w pass -b cn=b,dc=example,dc=com # b, example.com dn: cn=b,dc=example,dc=com objectClass: top objectClass: person cn: b sn: b # numResponses: 2 # numEntries: 1 With rwm, requesting an attribute (notice the object is not returned here): ldapsearch -x -D cn=a,dc=example,dc=com -w pass -b cn=b,dc=example,dc=com sn # numResponses: 1 With rwm, requesting an attribute and openldapaci (works as expected): ldapsearch -x -D cn=a,dc=example,dc=com -w pass -b cn=b,dc=example,dc=com sn openldapaci # b, example.com dn: cn=b,dc=example,dc=com sn: b OpenLDAPaci: 1#entry#grant;r,s,c;[all]#access-id#cn=a,dc=example,dc=com # numResponses: 2 # numEntries: 1 3) The last issue came up when I was attempting to set up a certain kind of access control logic. It is highly similar to the previous problem but it doesn't involve ACIs. The issue is caused by the rwm overlay somehow blocking the ACL from accessing unrequested attributes just like in the previous case. olcExtraAttrs was created to fix this issue but I assume it would not fully solve the problem in my case. I have naturally not been able to test it due to the fact that I haven't gotten olcExtraAttrs to work. The access control logic I was attempting to set up was such that objects could contain 2 new attributes: 'rights' and 'requiredRights', both being multivalued strings. 'requiredRights' tells what rights are required to access the object in question, and 'rights' tells what rights each object has. If the user's 'rights' and the target objects 'requiredRights' have at least one common string, access is granted. Fairly simple. The ACL used to evaluate access is as follows: to * by set="this/requiredRights & user/rights" read This method works unless I use the rwm overlay. I'm guessing the attributes required to evaluate the ACLs are somehow dropped and cannot be used. olcExtraAttrs would (if it worked) automatically add the needed attributes to the target object but, to my understanding, not to the user object. The user's attributes would however be needed to evaluate the set shown earlier. The trick used in the last of the previously shown search examples does not work in this case. I can provide requiredRights and rights as additional attributes in the search and I assume requiredRights is returned for access control to use but rights isn't as it is an attribute of the user object. I don't have a cleaned-up version of the config at this time but one could be created if needed.
