[389-users] DNA Plugin creating duplicates

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
