There are no specifications for protocol-level locking in either the X.500
standard nor the LDAP standard. Directories are not RDBMSs.
Your use case makes no sense. Once you've read the entry, you can do
calculations you want with that entry's data. Why does the entry in the
directory need to be locked?
==>There are ways for applications to perform cooperative locking in LDAP,
far it's not clear why you need it.
Actually i am using a DN
It is having a single attribute userId. And i want to use this attribute for
other entries of User
for an Example:
when a request for adding a information of any user comes that time i read
the value of userId and update this value by One
means now it is having value of userId
But between the process of reading and updating if some other request also
reads the value of userId: 5000 then both users have the same value.
But we don't want this.
so is there any mechanism through which we can hold the request,so it dose
not get the value of userId between the process of reading and updating.
You told me in your reply:
"There are ways for applications to perform cooperative locking in LDAP"
Please tell me about locking.
