LDAP account status

Hi, I want to disable an account without deleting informations about it. This account is linked with some services such as Owncloud, ftp authentification, samba, linux auth and ssh auth. Does it exists a way to disable the account for all the services? I know that I can disable the account for samba with sambaAcctFlags but I don't know an easy way for other services.

I thinked to create a new field called "AccountStatus" and filter on each service accounts which have AccountStatus=active like that

/(&(objectClass=inetOrgPerson)(AccountStatus=active))

/Is it a good way to do it or no?

Thanks
