[Samba] Attribute userParameters in samba 4 can't be modified

[Trenta sis]

Hi,

Trying to migrate samba3 to samba 4 ad, we have detected that ldap
attribute "userParameters" can't be modified, we receive:

"

LDAPException: Violación Del Constreñimiento (19) Violación Del Constreñimiento
LDAPException: Server Message: 0000202F: samldb: setting
userParameters is not supported over LDAP, see
https://bugzilla.samba.org/show_bug.cgi?id=8077 at
../source4/dsdb/samdb/ldb_modules/samldb.c:3104


"

How can I solve this, I need to migrate this configuration...

thanks
