Nexenta (Solaris), strange user membership from LDAP

Why do run id command in the Nexenta OS (Solaris+Ubuntu), I get different result? a_ay@nexenta:/etc$ id -G 513 512 1000 201 203 1010 1013 1019 1020 1036 1039 1040 1041 1045 1046 1047 a_ay@nexenta:/etc$ id -G a_ay 513 1019 1041 1047 512 1039 1036 201 3333 1000 1013 1020 1046 1057 1100 1040 1045 1048 203 1010 Moreover, I'm having a membership in one of the secondary group (1048) and I can not enter to the folder 'Folder' with GID permission is 1048. drw-r-xr-x 1 1062 1048 0 Apr 12 16:13 Folder All users in LDAP. *gentent group* work fine, and get all users correct. root@nexenta:/tmp# getent group | grep 1048 mygroupname::1048:a_ay,fred,john,superman
