Linux ID command

Try

#getent passwd lstarn

This will give you the extact id which is being populated by LDAP

TY/SA

here is the output

[root@linuxconsole ~]# getent passwd lstarn
bin:$1$tApqDl$5/wR5/6.9YD3l7KeKnoyc1:1:1:bin:/dev/null:/sbin/nologin

This problem occurs only on one particular server that is 'linuxconsole" server, same id works fine on other servers.

output from working server.
getent passwd lstarn
lstarn:*:80279:1091:Laurence Starn:/home/lstarn:/bin/bash

Same LDAP id is not used by local users on the server. here is the output of /etc/passwd
