<br>
The difference between the first and the second command could be the UID used for the resolution. The first command calls getgroups() syscall using the UID of the shell. The second command resolves johndoe UID through nsswitch stack then looks after the groups of this UID.<br>
<br>
Do you have johndoe declared in both local /etc/passwd and LDAP directory with different UID?<br>
<br>
Do `id` and `id johndoe` return the same UID?<br>
