Hi Gergo,

It didn't worked. Let's see If I did everything correctly:

1)
[root@ce02 defaults]# cat /opt/bdii/etc/bdii-update.conf
GIP file:///opt/glite/libexec/glite-info-wrapper
(Is this step really needed? CE is still on globus-mds and the site-bdii 
is running in other machine...)

---*---

2) 
[root@ce02 defaults]# cat /opt/glite/libexec/glite-info-wrapper
#!/bin/sh

export LANG=C
/opt/glite/libexec/glite-info-generic 
/opt/glite/etc/gip/glite-info-generic.conf

---*---

3)
[root@ce02 defaults]# cat /opt/glite/etc/gip/glite-info-generic.conf
temp_dir = /opt/glite/var/tmp/gip
cache_dir = /opt/glite/var/cache/gip
lock_dir = /opt/glite/var/lock/gip
plugin_dir  = /opt/glite/etc/gip/plugin
static_dir =  /opt/glite/etc/gip/ldif
provider_dir = /opt/glite/etc/gip/provider
freshness = 60
cache_ttl = 300
response = 110
timeout = 150

---*---

4)
[root@ce02 defaults]# cat /opt/glite/etc/gip/plugin/glite-info-dynamic-ce
#!/bin/sh
/opt/lcg/libexec/lcg-info-dynamic-sge

---*---

Running as edguser the command "/opt/glite/libexec/glite-info-generic 
/opt/glite/etc/gip/glite-info-generic.conf" I get proper/updated info.
Doing ldap query to port 2135 of ce02.lip.pt, I don't get updated info. 
lcg-info-generic is still installed and I guess it is still using it. 
How do I switch?
Cheers
Goncalo
