jul 05 18:41:06 - ERROR - Error while modifying entry
cn=uidNumberSequence,ou=HiddenTree,dc=azertyuiop,dc=local in directory
:javax.naming.directory.NoSuchAttributeException: [LDAP: error code 16
- modify/delete: serialNumber: no such value]; remaining name
'cn=uidNumberSequence,ou=HiddenTree'
[...]
That's a bit strange because
cn=uidNumberSequence,ou=HiddenTree,dc=azertyuiop,dc=local already
exist on the openldap server (we created it)
And serialNumber increase every time we execute the synchronisation
ldapsearch -LLL -h 127.0.0.1 -p 389 -D
'cn=xxxxxx,dc=azertyuiop,dc=local' -w xxxxxxxx
'cn=uidNumberSequence,OU=HiddenTree, dc=azertyuiop, dc=local'
dn: cn=uidNumberSequence,ou=HiddenTree,dc=azertyuiop,dc=local
cn: uidNumberSequence
objectClass: device
objectClass: top
serialNumber: 1108
This is not an issue. The error is not "invalid attribute" but "no such
value". When you try to increment an attribute, the LDAP operation is
something like that:
delete: serialNumber
serialNumber: 1108
-
add: serialNumber
serialNumber: 1109
The two operations must be done atomically. So if an other application
updates the serialNumber between when you read the value "1108" and when
you send the update, then the update is refused.
To fix this you can:
- try to catch the error and retry
- disallow other applications updates
If LSC is the only application, you should run it with only one thread
(option -t 1).
