Next Release of LMDB
by Vishesh Handa 03 Jun '15

03 Jun '15

Hey guys Is there some kind of rough timeline for when the next version of LMDB will be released? We're using it in KDE and we need the patch for robust mutexes, which is currently in git. I'm not too comfortable in asking all the distributions to have that patch, though opensuse already does that. -- Vishesh Handa

deleting pwdPolicySubentry attribute
by David Magda 03 Jun '15

03 Jun '15

Hello, "pwdPolicySubentry" is an operational attribute per slapo-ppolicy(5). I was able to add it quite easily, but I can't seem to delete it so an account goes back to using the default policy: $ ldapsearch -H ldap://master -W -D 'cn=admin,dc=example,dc=com' -b 'dc=example,dc=com' '(uid=dmagda)' + Enter LDAP Password: # dmagda, People, example.com dn: uid=dmagda,ou=People,dc=example,dc=com structuralObjectClass: inetOrgPerson entryUUID: 1b0d0b6c-1115-1030-8396-1ba5239e5e7d creatorsName: cn=admin,dc=example,dc=com createTimestamp: 20110512185510Z pwdPolicySubentry: cn=service,ou=pwpolicies,dc=example,dc=com entryCSN: 20150602173051.854144Z#000000#000#000000 modifiersName: cn=admin,dc=example,dc=com modifyTimestamp: 20150602173051Z entryDN: uid=dmagda,ou=People,dc=example,dc=com subschemaSubentry: cn=Subschema hasSubordinates: FALSE $ cat del.ldif dn: uid=dmagda,ou=People,dc=example,dc=com changetype: modify delete: pwdPolicySubentry $ ldapsearch -H ldap://master -W -D 'cn=admin,dc=example,dc=com' -f del.ldif Enter LDAP Password: [...] # search result search: 2 result: 32 No such object Given that I could add the attribute, was thought that it could be deleted as well. Thanks for any info. Regards, David

slapadd 4096-character LDIF line length limitation
by Kartik Subbarao 01 Jun '15

01 Jun '15

I wanted to ask if someone could shed some light on the 4096 character LDIF line length limitation, which seems to have been introduced sometime after 2.4.25. I learned about this the hard way, while trying to slapadd an LDIF file with long jpegPhoto attributes (e.g. 50K+) which loaded just fine on 2.4.25. Now, I get this error: ldif_parse_line: jpegPhoto: invalid base64 encoding char (556b9f15 <= str2entry: str2ad(....) slapadd: could not parse entry (line=14) When I need to preprocess LDIF files before loading them with slapadd, I often remove line continuations in order to simplify pattern matching. So of course from my perspective, it would be great to have the previous behavior back again. But if there are compelling reasons for the current behavior, I'd like to suggest that the code print a better error message that explicitly mentions the line length limit. Regards, -Kartik

LDAP schema issue
by Leander Schäfer 01 Jun '15

01 Jun '15

Hi This is the current relevant part of my schema: attributetype ( objectClassAccount:1.1 NAME 'mailAddress' DESC 'The hosted mail addresses' EQUALITY caseIgnoreIA5Match SUBSTR caseIgnoreIA5SubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.26{256} SINGLE-VALUE ) 1. How can I achieve, that upper case will always and only be stored as lower case? 2. How do I achieve a validation check whether the value is actually a valid email addres - very simple: user(a)domain.tld? Thanks & Best regards Leander

Create Mailing List
by Jerry 01 Jun '15

01 Jun '15

Is it possible to create a "mailing list" in openldap? My MUA allows me to create an alias like "MyGroup" that would then contain all the email addresses of the people in the group. I can then simply type that alias and it is replaced by the actual email addresses. I am looking for something like that in openldap. I realize that I can associate multiple email addresses to a single name; however, only one address can be chosen at a time. -- Jerry
