(ITS#5512) Doc contribution for search privileges in 2.4
by jclarke＠linagora.com 14 May '08

14 May '08

Full_Name: Jonathan Clarke Version: 2.4 OS: URL: Submission from: (NULL) (88.167.76.100) Hello, ITS #5400 outlines a change in the privileges required by search operations in 2.4. I would like to suggest documentation for this in the admin guide (the slapd.access man page is already accurate). Please find propositions here: 1) http://www.phillipoux.net/jonathan-clarke-20080515-upgrading.patch Explanation and example in the "Upgrading from 2.3" appendix. 2) http://www.phillipoux.net/jonathan-clarke-20080515-access-control.patch Detail of the required privileges on the "entry" pseudo-attribute in the access control section (static and dynamic config - same text is repeated twice). As a side note, I encountered a "452 Error writing file: No space left on device." error on ftp.openldap.org/incoming while trying to upload these patches. Regards, Jonathan

Full_Name: Dan White Version: 2.4.9 OS: Debian Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (2610:b8:1:0:21a:70ff:fe8f:e0b3) I'm experiencing SIGABRT crashes when the slapo-unique overlay is enabled, and I attempt to set one of the unique attributes to '0'. A configuration snippet: ... modulepath /usr/lib/ldap moduleload back_bdb moduleload smbk5pwd moduleload unique ... overlay unique #unique_base ou=People,dc=olp,dc=net unique_attributes uidNumber btcAltUID I'm triggering the crash while modifying the uidNumber attribute with the ldapmodify command: hiro:/var/lib/ldap# ldapsearch -LLL uid=dwhite(a)olp.net uidNumber dn: uid=dwhite(a)olp.net,ou=people,dc=olp,dc=net uidNumber: 497913425 hiro:/var/lib/ldap# ldapmodify dn: uid=dwhite(a)olp.net,ou=people,dc=olp,dc=net changeType: modify replace: uidNumber uidNumber: 0 modifying entry "uid=dwhite(a)olp.net,ou=people,dc=olp,dc=net" ldap_result: Can't contact LDAP server (-1) If I comment out all the unique overlay related configuration items and restart slapd, and rerun my ldapmodify command, the process completes normally.
