In Identity Manager secondary group on "UNIX v2 (DYN Endpoint)" endpoint is shown incorrectly as "awk".
Identity Manager 14.5
Endpoint: UNIX v2 (DYN Endpoint) / Solaris 11.4
The awk command on the target system has limit on number of characters in the string it can work with (in this particular case it was around 2500). When number of users on a certain group exceeds some limit, the string in the /etc/group file representing this group becomes too long and it leads to an error. Part of the error message is then interpreted by the Identity Manager as a group name.
Remove/workaround the limit on maximum number of characters in the string in the awk command. For example, by replacing original file (or link) /usr/bin/awk with a symbolic link to ../gnu/bin/awk or other awk implementation.
