LDAPSearch and modifyTimestamp range

[Alexander Hartner <alex@j2anywhere.com>]

I am trying to search a range of entries by their modifytimestamp,  
but I haven't figured out how to specify a range between dates. It  
works when I don't specify a range, but as soon as I add a range it  
fails with Bad Search Filter -7.

wolf:~ alex$ ldapsearch -D "..." -w ... -x -b "..." "modifytimestamp"
# extended LDIF
#
# LDAPv3
# base <o=j2anywhere,c=uk> with scope sub
# filter: (objectclass=*)
# requesting: modifytimestamp
#

# j2anywhere, uk
dn: o=j2anywhere,c=uk
modifyTimestamp: 20051010194035Z
...

wolf:~ alex$ ldapsearch -D "..." -w ... -x -b "..."  
"modifytimestamp>=2006030*"
# extended LDIF
#
# LDAPv3
# base <o=j2anywhere,c=uk> with scope sub
# filter: modifytimestamp>=2006030*
# requesting: ALL
#

ldapsearch: ldap_search_ext: Bad search filter (-7)

Thanks in advance
