Hi,

This has been spoken about before on the OpenLDAP lists, and the following is the method adopted by most of the commercial support companies, including my own (But your circumstance may defer).

The best way to handle this, is to handle it in OpenLDAP directly.

See:

• RE: compare uidNumber in LDAP
• Re: Get Max uidNumber ...
• RE: Uid/Gid Question

Basically, you create an entry like so:

    dn: cn=maxUid,dc=example,dc=com
    objectClass: extensibleObject
    objectClass: top
    uidNumber: 500
[download]

And then do the following ldapmodify with every new entry added:

    dn: cn=maxUid,dc=example,dc=com
    changetype: modify
    delete: uidNumber
    uidNumber: 500
    -
    add: uidNumber
    uidNumber: 501
[download]

Then you can just do a search to see the latest number.

HTH,

Gavin.
