DPM 1.6.4 and SL4

I have just come across a problem with running DPM v1.6.4 on SL4. Well, it's not actually a problem with DPM itself, but rather a problem with the BDII that it is now using as an information provider. SL4 comes with openldap v2.2 which appears to have stricter schema checking than openldap v2.0 (which comes with SL3). This causes problems like this:

$ ldapsearch -LLL -x -H ldap://wn4.epcc.ed.ac.uk:2170 -b mds-vo-name=resource,o=grid
Invalid DN syntax (34)
Additional information: invalid DN

Meaning that your SE can't publish anything about itself. This can be resolved by adding this block of code

attributetype ( 1.3.6.1.4.1.3536.2.6.1.4.0.1
NAME 'Mds-Vo-name'
DESC 'Locally unique VO name'
EQUALITY caseIgnoreMatch
ORDERING caseIgnoreOrderingMatch
SUBSTR caseIgnoreSubstringsMatch
SYNTAX 1.3.6.1.4.1.1466.115.121.1.44
SINGLE-VALUE
)

to /opt/glue/schema/ldap/Glue-CORE.schema and then restarting the ldap and bdii processes. This is covered by this bug:
