[389-users] Re: DNA Plugin creating duplicates

I does not look like I have that Matching Rule configured on those indexes.

Thanks, that's a good thought. It looks like I do have the index set up though.

dn: cn=uidnumber,cn=index,cn=userroot,cn=ldbm database,cn=plugins,cn=config
cn: uidnumber
nsIndexType: eq
nsSystemIndex: False
objectClass: top
objectClass: nsIndex

Does the index also need to support nsMatchingRule: integerOrderingMatch for inequality searching?

It has been a long time since I set this up and I am running an older version of the server but I did find this in my notes:

Before assigning a number to a new entry the DNA plugin searches the directory to ensure that the number is not already being used. For this reason indexes had to be created for all of the attributes which the DNA plugin can assign values to.

Perhaps that is it?

Hi,

I'm running 389ds 2.0.15 on a two node cluster in a multi master mode. I'm using the DNA plugin to generate unique uid numbers for new accounts. Each directory instance is assigned a unique range of uid numbers. It works in so far as it assigns a uid number when it gets the magic token but whatever is supposed to be verifying that the uid number is not already assigned is not working. I've cranked the error log level up, but I don't get anything in the logs that is helpful in determining why that validation is not working correctly. 

# ansible-managed-uidnumber-generation, Distributed Numeric Assignment Plugin,
 plugins, config
dn: cn=ansible-managed-uidnumber-generation,cn=Distributed Numeric Assignment
 Plugin,cn=plugins,cn=config
objectClass: top
objectClass: dnaPluginConfig
cn: ansible-managed-uidnumber-generation
dnaType: uidNumber
dnaNextValue: 62009
dnaMaxValue: 131000
dnaMagicRegen: generate
dnaFilter: (objectclass=posixAccount)
dnaScope: ou=Accounts,dc=example,dc=edu
dnaSharedCfgDN: ou=ranges,ou=Accounts,dc=example,dc=edu

I'm stumped. Anyone have any direction on how to debug this further?

Thanks!
Todd
