id <username>, results no such user

When run id <user name>, give result no such user
rcnamcd is working. Lum is configured properly.  When do id admin it gives required result, but when do id <user name> result no such user
.Checked the userlist and grouplist and the entry of the users were there.
The unix workstation objects point to the groups that have rights to the linux workstation and there were two groups (same name- admingroup), in different containers with the same group id number
 This can cause a conflict

id admin gives result but id <user name> did not give any results.<no such user>

*Check rcnamcd is running.  rcnamcd status.
*Check LUM is configure properly.<iManager>
*Check userlist and grouplist if the users entry is there or not. if not then do the entry.
    namuserlist -x o=<OU name>
    namgrouplist -x o=<OU name>
The users entry should be there.
*Check the base dn in nam.conf file. <This is the context where it starts looking for the unix config object>
*The base dn in that file should be the dn where the unix config object is in the tree.
*Check if there could be two group of same name in different container with the same group id number.This can cause confilct.
    If yes then, Delete one group of the same name.
*Need to have rights to browse the tree and read Linux attributes. If do not have browse rights for {public] then modifiy trustee of ROOT of the tree and gave [public] browse rights to find lum enabled users.

After doing any changes restart rcnamcd.
