Yes, since your mileage may vary.

You could try to let the OpenLDAP libs handle the referral by setting:

ldap.set_option(ldap.OPT_REFERRALS,1)

Note that referral handling in OpenLDAP libs is considered to be broken.

You could try to handle the referral by catching the exception ldap.REFER=
RAL=20
which contains the LDAP URL of the referred LDAP entry/server:

ldap.set_option(ldap.OPT_REFERRALS,0)

You can dig into the source code of web2ldap to find out how I'm doing it=
=2E=20
Try to provoke the same situation with web2ldap to see what happens.=20
web2ldap asks for a new login when following a referral.

Not sure since this depends on server configuration. You have to find out=

yourself what really happens in your environment.
