Title: Slapd errors? in syslog
Post by: auerhaan on February 15, 2010, 09:57:25 pm

I have this error in my syslog from time to time:

Quote

Feb 15 21:38:08 ubuntu01 slapd[7927]: conn=57599 op=17 do_search: invalid dn: "sambaDomainName=,sambaDomainName=AUERHAAN-WG,dc=ebox"

Looks like there is a request that isn't build up properly sambaDomainName=,sambaDomainName=

There are also a lot messages like these:

I'm also getting SLAPD messages en syslog, such as:

slapd[8570]: <= bdb_equality_candidates: (mail) not indexed

slapd[8570]: connection_read(22): no connection!


Any help??

same problem here, have been looking for problems and errors but got no result.
As I have EBox on one of my production system, please resolve this quickly!

This is a harmless error, you can just ignore it.

Harmless unless you have thousands of entries isn't it?
I mean lack of index will impact performance (both in term of response time and load on server).
For what I've experienced with other LDAP distributions, up to few hundreds of entries will not make significant difference whenever attribute is indexed or not. This assuming you don't have too many requests... but this should match the fact that you don't have too many user entries neither.

Am I correct?

To remove the 'bdb_equality' warnings you could follow this instructions:

Have you any clue of when this errors appear? Is something random or is always after a specific operation?.

According to http://trac.ebox-platform.com/wiki/Document/HowTo/LDAPoptimization (http://trac.ebox-platform.com/wiki/Document/HowTo/LDAPoptimization) you have to modify

Code: [Select]

$ sudo vim /etc/ldap/slapd-frontend.d/cn\=config/olcDatabase\=\{1\}hdb.ldif
$ sudo vim /etc/ldap/slapd-translucent.d/cn\=config/olcDatabase\=\{1\}hdb.ldif
$ sudo vim /etc/ldap/slapd-replica.d/cn\=config/olcDatabase\=\{1\}hdb.ldifwhich no longer the case as slapd schema has changed.

Below worked for me:
Stop slapd:

Code: [Select]

$ sudo /etc/init.d/slapd stopModify config to include additional indexes

Code: [Select]

$ sudo nano /etc/ldap/slapd.d/cn\=config/olcDatabase\=\{1\}hdb.ldifFind

Code: [Select]

olcDbIndex: objectclass eq
olcDbIndex: entryCSN eq
olcDbIndex: entryUUID eq
olcDbIndex: uid eq
olcDbIndex: memberUid eqReplace with

Code: [Select]

olcDbIndex: objectClass eq,pres
olcDbIndex: ou,cn,sn,mail,givenname eq,pres,sub
olcDbIndex: uidNumber,gidNumber,memberUid eq,pres
olcDbIndex: loginShell eq,pres
olcDbIndex: uniqueMember eq,pres
olcDbIndex: uid pres,sub,eq

olcDbIndex: sambaSID eq
olcDbIndex: sambaPrimaryGroupSID eq
olcDbIndex: sambaDomainName eq
olcDbIndex: sambaGroupType eq
olcDbIndex: sambaSIDList eqSave.
Index:

Code: [Select]

$ sudo slapindex
