Actually i am using a DN
dn: guid=userId,dc=example,dc=in userId: 5000
It is having a single attribute userId. And i want to use this attribute for other entries of User for an Example:
dn: userName=rkyadav,dc=example,dc=in userName: rkyadav userId: 5000
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
dn: guid=userId,dc=example,dc=in userId: 5001
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.
